Transcript for Vice President Mike Pence thanks National Guard for protection, inauguration
And just before we came on the air this evening, vice president Mike pence and an unscheduled stop at the capitol to visit National Guard troops. And what's next now for president trump, with a senate trial next after being impeached a second time. What we're now hearing from some Republican senators. And what message is the majority leader Mitch Mcconnell sending by leaving open the possibility that he could vote to convict? Here's our chief white house correspondent Jon tan Karl. Reporter: Tonight, vice president Mike pence made a surprise visit to capitol hill, thanking the National Guard troops who will be protecting the inauguration. Have a safe inauguration and I just wanted to stop out today to say thank you. Reporter: Spotted at 1600 Pennsylvania avenue, moving trucks. Donald Trump's aides seen packing up and moving on, one person carrying a bust out of the west wing. As house Republicans who broke ranks and voted to impeach the president are facing the fury of trump loyalists. Congressman Peter meijer of Michigan, the only freshman Republican who voted to impeach, says some of his colleagues fear for their lives and are traveling with armed escorts. Many of us are altering our routines, working to get body armor. It's sad that we have to get to that point, but our expectation is that someone may try to kill us. Reporter: Liz Cheney, the most prominent Republican yes vote on impeachment, is fighting for her political life. She said of trump, "There has never been a greater betrayal by a president of the united States." Today, congressman Jim Jordan and other diehard trump supporters circulated a petition calling for her to be booted out of her leadership position, saying that she, quote, brought the conference into disrepute and produced discord. But a spokesperson for Kevin Mccarthy said the Republican house leader opposes the move to remove Cheney. Mccarthy, who has been one of trump's most loyal supporters, opposed impeachment, but he also placed blame on trump for the capitol riot. These facts require immediate action by president trump, accept his share of responsibility, quell the brewing unrest and ensure President-Elect Biden is able to successfully begin his term. Reporter: Late last night, a full week after the riot, trump told his supporters to be calm and nonviolent. Mob violence goes against everything I believe in and everything our movement stands for. Reporter: This after he riled them just before the riot began. We fight like hell and if you don't fight like hell, you're not going to have a country anymore. Reporter: He still hasn't taken any responsibility whatsoever for inciting the violence, insisting his words were totally appropriate. Now it's up to the senate to judge whether that's true. The trial will likely begin just after the inauguration. It will take 17 Republicans, and all of the Democrats, to convict. Senator Lisa murkowski says the president deserved to be impeached. I believe that this president has committed an impeachable offense. Reporter: Still, murkowski has not said whether she'll vote to convict, but she did declare that trump's unlawful actions cannot go without consequence. Jon, those words from Lisa murkowski. But we know so much attention on the majority leader, for a few more days, Mitch Mcconnell. You know before the president's first impeachment trial, Mcconnell said he wouldn't be an impartial witness. This time, Mcconnell saying he has not made a final decision on how he will vote. I'm curious from your reporting what message he is sending to not only his fellow Republicans in the senate but the message he's trying to send to the president. Reporter: Mitch Mcconnell, David, is sending an unmistakable message to senate Republicans and to the president that this time, he is not going to bail out Donald Trump. Whether he ultimately votes to convict is anybody's guess but he is certainly not going to defend him this time, David. All right, Jon Karl with us again tonight.
