Trump 2nd term live updates: Trump defends tariffs, declines comment on Ukraine aid

The United States and Ukraine could sign the minerals deal as soon as Tuesday, according to two sources briefed on the discussions.

The deal was originally expected to be signed Friday at the White House, but talks quickly went downhill, and Trump kicked Ukrainian President Volodymyr Zelenskyy out of the White House without completing the agreement.

Sources caution that nothing is final. However, Trump has indicated to top advisers he would like to get the deal done before his joint address to Congress.

Senate Democrats blasted President Donald Trump's first month in office ahead of his address to a joint session of Congress, gathering for a news conference on Tuesday while holding up photos of the guests they're bringing to the speech, including fired bureaucrats and others who have been negatively affected by the White House's moves to slash the federal workforce.

"We think one of the best ways to let the American people know how horrible Donald Trump's first 30 days have been is to bring those who have been affected, the victims of his malevolence, of his desire, the tax breaks for the billionaires and make Americans pay for it," Senate Minority Leader Chuck Schumer, D-N.Y., said on the Senate steps.

"Americans who voted for the president didn't sign up for this. They wanted lower costs. ... What is the State of the Union, we ask? Chaos is up, corruption is up, and costs are up for regular people," Sen. Amy Klobuchar, D-Minn., added.

Sen. Thom Tillis, R-N.C., is wearing his Ukraine pin and a navy blue suit with yellow tie ahead of President Donald Trump's address to the joint session of Congress.

Tillis is a staunch ally of Ukraine who has become increasingly outspoken about his support for the country as the riff between Ukraine and the Trump administration has widened.

"I'm trying to figure out what it would feel like to have been the head of state for a country that has experienced systematic murder rape, kidnapping and torture of tens of thousands of people, and I actually think somebody under that pressure should be given a little bit of leeway when it comes to addressing frustration," Tillis said.

The Office of Personnel Management has revised its Jan. 20 memo to federal agencies about probationary employees -- now writing that "OPM is not directing agencies to take any specific performance-based actions regarding probationary employees."

"Agencies have ultimate decisionmaking authority over, and responsibility for, such personnel actions," read the memo, which came after a federal judge ruled last week that the OPM's initial directive to terminate temporary employees was illegal.

An OPM spokesperson did not respond to questions about how this change affects workers who have already been fired -- or if this is meant to bring the government's directives in line with the new ruling.
