One week after addressing the nation for the first time as president-elect from Wilmington, Delaware, Joe Biden has penned an open letter to his home state published by the Delaware News Journal, thanking its denizens for helping him get to the Oval Office after nearly 50 years in public life.

“This election was won by bringing Americans from all walks of life together. It was won because of the hard work and faith of so many people across this country. It was won with a promise to restore the soul of this nation and build back better than ever. However, we never could have done it without you -- without Delaware,” Biden wrote in the letter, which the publication said it asked him to write.

As he often did on the trail, Biden spoke about the values he learned growing up, and the president-elect offered the same unity pitch he delivered last week.

“Our country has never needed the values I learned here in Delaware more. That’s why, although I am a proud Democrat, I promise you, I will be an American President, and work as hard for those who didn’t vote for me, as those who did,” he said.

As pro-Trump protesters gathered in Washington, D.C., on Saturday, President-elect Biden and his wife, Jill Biden, went out for a bike ride in Delaware's Cape Henlopen State Park. 

On Thursday, Biden traveled from Wilmington to Rehoboth Beach, Delaware, where the Bidens own a vacation home and where he has continued meeting with transition advisers, according to the Biden campaign.

Meanwhile, Trump was seen arriving at Trump National Golf Club in Virginia, met by protesters rallying against him.

Pro-Trump protesters were seen gathering in Washington, D.C., on Saturday, cheering Trump's motorcade as it passed. The president on Friday had teased an appearance at planned demonstrations.

Trump was spotted in golfing attire, waving from the motorcade as enthusiastic supporters chanted "USA." 

Supporters also waved Trump flags and carried signs, chanting “Four More Years” and “Stop the Fraud.”

Demonstrators protesting Trump were also seen gathered at Trump National Golf Club as the president's motorcade arrived.

A dinner planned for new members of the House as part of their orientation week Friday night was canceled after backlash on Twitter. 

When a reporter with NBC tweeted a photo of Statuary Hall in the Capitol, filled with tables, and an assurance from House Speaker Nancy Pelosi that it was safe, some saw it as hypocritical for leaders to gather to break bread as Americans were being told it's not safe for them to get together with family for Thanksgiving.

Pelosi's office eventually announced that members wouldn't be having dinner in the Capitol, but taking their boxed meals to go.
