The Latest on President Donald Trump's trip to Europe (all times local):
President Donald Trump has jolted the NATO summit in Brussels by turning a spotlight on Germany's ties to Russia and openly questioning the value of the military alliance that has defined American foreign policy for decades.
Trump declared that a joint natural gas pipeline venture with Moscow has left German Chancellor Angela Merkel's government "totally controlled" by and "captive to Russia."
Trump tweeted after a day of contentious meetings, "What good is NATO if Germany is paying Russia billions of dollars for gas and energy?"
Merkel hit back immediately, not only denying Trump's contention but suggesting that his comfortable upbringing in the U.S. gave him no standing to spout off on the world stage about Germany.
Poland's President Andrzej Duda and President Donald Trump have spoken on the sidelines of a NATO summit in Brussels about strengthening military cooperation.
The talk Wednesday comes as Poland is lobbying to have thousands of American troops permanently stationed in Poland as a deterrent against a resurgent Russia. According to news reports in Poland, the Warsaw government has offered up to $2 billion to help build the infrastructure for the permanent deployment.
The head of Duda's office, Krzysztof Szczerski (KSHISH-tof SHARE-ski), told the state Polish news agency PAP that the leaders spoke "mainly about military cooperation, including the strengthening of Polish-American military cooperation in the field of equipment and cooperation of military units."
The meeting marks a significant improvement of ties between the two countries after Poland recently softened a controversial Holocaust speech law that the U.S. had strongly opposed. Poland scrapped the threat of prison terms for claiming Poland is co-responsible for the Holocaust, but civil penalties can still apply.
President Donald Trump and first lady Melania Trump are attending a dinner for NATO leaders in Brussels.
The gathering comes just minutes after Trump tweeted "what good is NATO" amid a day of grievances about the decades-old alliance.
The Trumps arrived at the Art and History Museum at the Cinquantenaire and first mingled with other leaders at a cocktail reception.
Neither Trump took a drink as they chatted with other heads of state. The president does not drink alcohol.
The Trumps were seen mingling with German Chancellor Angela Merkel hours after the president had criticized Germany for making a gas pipeline deal with Russia. They also spoke with President Recep Tayyip Erdogan (REH'-jehp TY'-ihp UR'-doh-wahn) of Turkey.
The leaders then posed for several group photos and took in an acrobatic performance before entering the dinner reception.
NATO Secretary-General Jens Stoltenberg is sidestepping questions about whether President Donald Trump has asked his allies to double their defense spending ambitions.
At a NATO summit in Brussels Wednesday, Trump suggested that U.S. allies should commit to spending 4 percent of their GDP on defense, up from the current goal of moving toward 2 percent by 2024.
Asked about Trump's suggestion, Stoltenberg said he'll focus on what's been agreed to. Says Stoltenberg: "We have agreed that we're committed to the pledge increasing defense spending to 2 percent. So let's start with that."
Around eight members of the 29-country military alliance are expected to reach the 2 percent target this year.
Trump's biggest target for criticism, Germany, predicts that it will be spending 1.5 percent of GDP on its military budget by 2024.
President Donald Trump is escalating his criticism of NATO while he is in Brussels for a summit with alliance leaders.
In a Wednesday tweet after a day of meetings, in which he lashed out at allies for insufficient defense spending, Trump calls on member nations to immediately boost spending.
Trump tweets: "Why are their (sic) only 5 out of 29 countries that have met their commitment? The U.S. is paying for Europe's protection, then loses billions on Trade. Must pay 2% of GDP IMMEDIATELY, not by 2025."
Contrary to Trump's assertion, NATO nations committed in 2014 to spending at least 2 percent of GDP on defense, but only by 2024.
Trump also tweets: "What good is NATO if Germany is paying Russia billions of dollars for gas and energy?" Trump earlier claimed that Germany was "totally controlled" and "captive to Russia" over a natural gas pipeline
The second most-powerful Republican in the U.S. Senate says he is sympathetic to President Donald Trump's assertion that Germany is "captive to Russia" because of its dependence on Russian natural gas and other energy sources.
Texas Sen. John Cornyn says he also wishes Germany "would step up and meet their responsibilities under NATO." Cornyn says it's pretty clear Germany has decided its relationship with Russia is important to them because Russia is their source of energy.
Cornyn said Trump was right to ask whether Germany is "perhaps pulling their punches" with regard to its support for NATO because of its dependency on Russia.
Cornyn says he understood what Trump was getting at with his use of the word "captive" but would not have used that specific word himself.
U.S. House Speaker Paul Ryan is defending NATO as "indispensable" after President Trump roiled a gathering of the alliance by sharply criticizing Germany.
The Wisconsin Republican says Trump is right to push NATO members to meet their defense spending obligations. But Ryan adds that the military alliance is "as important today as it ever has been."
Trump lashed out at German Chancellor Angela Merkel at a summit in Brussels. He claimed that Germany is "totally controlled" by and "captive to Russia" because of an oil and gas pipeline.
Asked if he agreed with Trump, Ryan said he's mentioned "those same concerns" to European leaders about the pipeline, which carries natural gas from Russia to Europe.
Republican U.S. Sen. Thom Tillis is heading to Brussels later Wednesday as part of the recently relaunched Senate NATO Observer Group. The group was re-established earlier this year with Democratic Sen. Jeanne Shaheen of New Hampshire in a show of bipartisan support for the alliance.
Tillis says "we have to let them know that Congress is supportive of NATO."
The North Carolina lawmaker adds that he supports President Donald Trump's goal of trying to get investment levels up, but says the "broader relationship" could benefit from some re-examination. He says he sees where Trump is trying to go, but suggests he maybe would use "different tactics."
And on Trump's comments about Germany, Tillis says he "wouldn't have said that."
President Donald Trump has suggested that NATO allies commit to spending 4 percent of their GDP on defense, up from the current goal of 2 percent by 2024.

Utah Republican Sen. Orrin Hatch says he disagrees with President Donald Trump's assertion that Germany is "totally controlled" and "captive to Russia."
The longest serving Republican U.S. senator says: "I don't agree with that. Germans wouldn't agree with that. They are a very strong people."
Hatch met with German Chancellor Angela Merkel when he traveled to Berlin last week. In Washington on Wednesday, he says: "I have the highest opinion of her. I think she's one of the great leaders of this world."

French President Emmanuel Macron says he disagrees with President Donald Trump's assessment that Germany is "totally controlled" by Russia because of an oil pipeline.
Macron was asked about Trump's assertion Wednesday as the leaders sat down for talks while both are attending a NATO summit in Brussels.
Trump has been hammering France and other European countries over their defense spending, as well as over trade deals he says are unfair to the U.S.
But Trump told reporters in the room for part of the meeting that he and Macron have a "tremendous relationship" and that it was an "honor to be with a friend of mine." He added that "hopefully in the end it will all work out."
Macron also recalled Trump's trip to Paris last year for a Bastille Day celebration and said they'll continue to work together.

The spouses were welcomed to the music center by Amelie Derbaudrenghien, the partner of Belgian Prime Minister Charles Michel, and Ingrid Schulerud, the wife of NATO Secretary-General Jens Stoltenberg. They toured the center and attended a piano and violin concert.
Other participating first ladies include Brigitte Macron of France and Emine Erdogan of Turkey.
President Donald Trump says he's thinking about American farmers even as he meets with NATO allies in Brussels.
Trump says in a two-part tweet Wednesday that he's "in Brussels, but always thinking about our farmers."
Critics have warned that Trump's antagonistic trade moves will harm American farmers who grow crops like soybeans.
But Trump says "Farmers have done poorly for 15 years" and blames "Other countries' trade barriers and tariffs" for "destroying their businesses." He's pledging to open "things up, better than ever before" but says "it can't go too quickly."
Trump says "I am fighting for a level playing field for our farmers, and will win!"
The tweet came as Trump attended a closed-door meeting of the North Atlantic Council. Staffers often send tweets for the president.

Trump and the queen will review the honor guard before watching a military parade. Trump and his wife will then have tea with the queen inside the castle.

Trump is taking issue with the U.S. protecting Germany when the European nation is making energy deals with Russia.
The president appeared to be referring to the Nord Stream 2 pipeline that would double the amount of gas Russia can send directly to Germany, skirting transit countries such as Ukraine. The project is opposed by the U.S. and some other EU members.
Trump says of Germany: "We're supposed to protect you against Russia" and yet you make this deal with Russia.
Stoltenberg pushed back, stressing that NATO members have been able to work together despite their differences.
