On ABC's "This Week," FiveThirtyEight's Nate Silver talks about the retribution seven Republican senators who voted in favor of former President Donald Trump's impeachment might face.

Biden is making a surprise visit to meet with his longtime Senate colleague Bob Dole in Washington, D.C., on Saturday.

Biden “is visiting his close friend,” according to the White House, following the 97-year-old’s announcement on Thursday morning that he had been diagnosed with stage 4 lung cancer. In a tweet, Dole said he would begin treatment on Monday.

First lady Jill Biden spoke virtually Saturday morning at the Student Veterans of America (SVA) National Conference, reflecting on her military family and thanking them for being “a force for change” in the United States.

“You are the voice of a generation who has carried the incredible weight of our wars for over 20 years. You speak up for each other. You get things done, and you show your brothers and sisters in arms what's possible," she said.

President Biden and Jill Biden’s late son, Beau, served in Iraq with the Army National Guard, and Jill Biden’s father was a Navy signalman in World War II. 

“Thanks to the GI Bill, he was able to go to business school in Philadelphia,” Biden said of her father. “Ever since my dad's time in service, our nation has made a promise to the courageous souls who take up arms for us, that your service will earn you the chance to pursue your education.” 

She said the commitment of the Biden administration is to “implement the Forever GI Bill with precision and care.”

“We're going to learn from your work, and develop best practices for supporting veterans in higher education,” she said.

Assisting military families has always been one of Jill Biden's main issues. During her time as second lady during the Obama administration, she and former first lady Michelle Obama led “Joining Forces,” a support program for military families, which Biden relaunched this year.
