Two Republican senators now say President Donald Trump should resign as support for the drive to impeach him a second time is gaining momentum in his final days in office after the deadly riot at the Capitol by a violent mob of Trump supporters.

Sen. Pat Toomey of Pennsylvania on Sunday joined Alaska Sen. Lisa Murkowski in calling for Trump to “resign and go away as soon as possible.” Murkowski, who has long voiced her exasperation with Trump’s conduct in office, told the Anchorage Daily News on Friday that Trump simply “needs to get out.”

Toomey said that even though he believes Trump committed impeachable offenses in encouraging loyalists in the Capitol siege on Wednesday, he did not think there was enough time for the impeachment process to play out. Toomey said that resignation was the “best path forward, the best way to get this person in the rear view mirror for us.” He was not optimistic that Trump would step down before his term ends on Jan. 20.

Key updates:

• Police charged more Capitol rioters on Saturday, including a man who carried off the House speaker’s lectern, as more graphic details of the insurrection emerged, revealing the violence and brutality of the mob that stormed a seat of American political power. A bloodied officer was crushed in a doorway screaming in Wednesday's siege. Another officer tumbled over a railing into the crowd below after being body-slammed from behind. Members of the media were cursed, shoved and punched.
• House Majority Whip Jim Clyburn says the House could vote this week to impeach President Donald Trump but delay sending the legislation to the Senate until after many of incoming President Joe Biden’s Cabinet secretaries are confirmed for their posts.
• Vice President Mike Pence will attend the inauguration of President-elect Joe Biden, according to a source familiar. Previous reports indicated that Pence was planning to attend the inauguration, but he was waiting on an invitation. Biden said Friday that Pence was welcome to attend. President Donald Trump announced on Twitter, before his account was suspended, that he would not be attending.
• Though stripped of his Twitter megaphone, President Donald Trump does have alternative social media options. The president of the United States also has a vast array of options to communicate with the American people that don't involve social media.

Oaths questioned as Trump's backers fight against loss

Before they take office, elected officials swear to uphold the U.S. Constitution. But what happens when they are accused of doing the opposite?

As some Republicans continued to back President Donald Trump's doomed effort to overturn the election, critics — including President-elect Joe Biden — accused them of violating their oaths and instead pledging allegiance to Trump.

The oaths, which rarely attract much attention, have become a common subject in the final days of the Trump presidency, being invoked by members of both parties as they met Wednesday to affirm Biden's win and a violent mob of Trump supporters stormed the U.S. Capitol.

“They also swore on a Bible to uphold the Constitution, and that’s where they really are stepping outside and being in dereliction of duty,” said former New Jersey Gov. Christine Todd Whitman, a Republican who served as EPA administrator during former President George W. Bush's administration. “They swore to uphold the Constitution against all our enemies, foreign or domestic, and they are ignoring that.”

In wake of Capitol riot, Americans struggle for answers

This past week, Americans watched as the hallowed chambers of the Capitol were overrun and defiled, not by some foreign enemy of democracy but a mob of their fellow citizens.

And then they tried to make sense of it.

In letters to the editor and posts on social media, they raised their voices. In Iowa, a lifelong Republican mourned the shredding of the country’s political norms. In Tennessee, a pastor and activist, alarmed by the rioters’ behavior, wondered if it might provide an impetus for change. In Mississippi, a young teacher worried what her students will make of the violence.

Days later, their anger, fear and uncertainties still linger. Answers have not come easily.
