Canadian Prime Minister Justin Trudeau shared details of his phone conversation Friday with President Joe Biden.

The two discussed "ending the pandemic, growing the middle class, fighting climate change, and creating good jobs for people on both sides of the border," among other issues, Trudeau tweeted, along with a photo of himself smiling while on the phone.

The two leaders "agreed to work shoulder to shoulder" to address the issues, Trudeau added, before congratulating Biden -- whom he referred to as "Joe" -- on the inauguration.

According to a readout of the conversation from Trudeau's office, the prime minister also raised Canada's "disappointment" over Biden's cancelation of the Keystone XL pipeline and urged the removal of softwood lumber duties that Trump imposed.

In its own readout of the conversation, the White House said that Biden "acknowledged" Trudeau's "disappointment" about the Keystone XL pipeline, and that the president "reaffirmed his commitment to maintain an active bilateral dialogue and to further deepen cooperation with Canada."

Trudeau and Biden agreed to meet next month "in order to advance the important work of renewing the deep and enduring friendship between Canada and the United States," the prime minister's office said.

Former President Donald Trump's acting Department of Homeland Security secretary is urging the Senate to confirm Joe Biden's nominee for the post.

In a letter Friday to the Senate Homeland Security Committee that was obtained by ABC News, Kevin McAleenan argued that due to the ongoing pandemic, immigration issues and U.S. national security interests, the Senate should vote to confirm Alejandro Mayorkas.

"There has been a long-standing, bipartisan commitment to ensure that a duly-elected President receives swift confirmation of the national security positions in his Cabinet. There should be no exception to this commitment today, when multi-faceted challenges and threats face our nation, and effective responses from our Federal Government are essential," wrote McAleenan, who also noted that domestic terrorism is an "increasing concern."

McAleenan also vouched for Mayorkas' credentials in his letter.

"After serving under his leadership during the Obama Administration, I know that Ali Mayorkas has the character, intellect, and integrity to serve as Secretary of Homeland Security," he wrote. "He has the humility to listen to his operational component leaders and has the character to make difficult decisions."

The Senate is not expected to take any additional votes on Biden appointees Friday, ABC News has learned.

That means Biden will head into his first weekend as president with only two Senate-confirmed appointees: Avril Haines, who was confirmed as director of national intelligence Wednesday, and Lloyd Austin, who was confirmed as defense secretary Friday.

The Senate left Friday without voting on the nomination of Janet Yellen to serve as treasury secretary. Her nomination unanimously passed out of the Senate Finance committee Friday morning. It's not clear why the Senate did not vote on Yellen.

The Senate will also leave for the weekend without voting on several other nominees who sat for confirmation hearings this week.

Senate Majority Leader Chuck Schumer blamed Senate Minority Leader Mitch McConnell for the stall.

"He's the one holding things up," Schumer said.

In a new letter to colleagues, House Speaker Nancy Pelosi says former President Trump will have had plenty of time to prepare for his upcoming Senate trial, which could start as soon as next week. 
Republicans have called foul over the fact that the impeachment in the House was rushed and now they want to give the former president until mid-February to mount his defense.

But Pelosi is making it clear that the article will be sent to the Senate on Monday and that the process will be fair to the former president.

"The House has been respectful of the Senate’s constitutional power over the trial and always attentive to the fairness of the process. When the Article of Impeachment is transmitted to the Senate, the former President will have had nearly two weeks since we passed the Article. Our Managers are ready for trial before the 100 Senate jurors," she writes in her letter.

Once the article of impeachment is delivered to the Senate Monday, the trial must start by Tuesday at 1 p.m. unless Senate Majority Leader Chuck Schumer and Minority Leader Mitch McConnell come up with an agreement that could give both sides more time to prepare.

In his appearance on ABC's "This Week" Sunday, Biden’s nominee for Surgeon General Vivek Murthy said that when it comes to meeting the goal for 100 million vaccines in the first 100 days of the president's administration, there are things that could go right or wrong.

"I think President Biden fully understands there's a larger goal here, as we all do, which is that we've got to vaccinate as many Americans as possible. And that's going to take a lot of work, work dispelling this disinformation, working on the supply, increasing distribution channels," he told ABC News Chief Anchor George Stephanopoulos. "And that's some of what the vaccine plan that he announced over the last week is intended to -- to achieve."

Stephanopoulos pressed Murthy on whether there are ways to increase the supply and equitably distribute the vaccines.

"It appears, at least in these first vaccines that have gone out, they've been going largely to wealthier areas of the country, largely to whiter areas of the country," Stephanopoulos said.

"Well, it's the right question, George, because success has to be gauged not just by the number of vaccines we deliver but also by how fairly we deliver those vaccines -- how equitably we deliver them," he said in response. "What we've got to do here is not just, again, increase supply, which we can do using the Defense Production Act ... but we've also got to set up the kind of distribution channels, like mobile units, like strategically placed community vaccination centers, that can reach people who traditionally are hard to reach and don't have access to health care."

He added, "We have got to track our progress. We have got to make sure that we have data on where the vaccine is being administered, so that we can ensure that it, in fact, is being distributed equitably."
