Transcript for Trump plans military-style send-off for himself on Inauguration Day
President trump out of sight today, but details about his plan to leave the white house, holding a military style farewell the morning of the inauguration. What now for the senate trial? Who will defend the president? And could there be anymore pardons? Here's Jonathan Karl tonight. Reporter: A little over a week of inciting a mob of his supporters to attack the U.S. Capitol, president trump is now planning an elaborate military-style sendoff for himself on the morning of the inauguration. Sources briefed on his plans tell ABC news the president hopes to depart to the sounds of a military band, walking down a red carpet flanked by troops as he boards air force one for the last time. He's even talking about a flyover by air force fighter jets. As trump plans his exit, he's left it to vice president pence to act like the actual commander-in-chief, reviewing inauguration security plans and visiting troops at the capitol. Have a safe inauguration, and I just wanted to stop out today to say thank you. Reporter: Soon after he leaves D.C, trump will find himself on trial in the senate. House speaker Nancy Pelosi hasn't yet decided when she'll deliver the article of impeachment that will trigger the start of the trial. You'll be the first to know when we announce that we're going over there. Reporter: The impeachment trial could begin the same day as the inauguration. But team Biden today insisted that won't stall their agenda. We know how to multitask. That's what's going to be required. Reporter: As house Democrats prepare their case against the president, speaker Pelosi today announced retired general russel Honore will lead an immediate review of capitol security, including whether any members of congress gave rioters access to the building the day before so they could plan their attack. If in fact it is found that members of congress were accomplices to this insurrection, if they aided and abetted the crime, there may have to be actions taken beyond the congress, in terms of prosecution. So, let's get to Jon Karl with us live from Washington. We know it's the last Friday night of the trump administration, the presidency. There's been a lot of speculation about whether we might see additional pardons in these final days. What are you learning from your sources tonight? What can we expect in terms of pardons? How is the president preparing for a second impeachment trial in his defense? Reporter: I will expect we'll see some more pardons. The big question is whether or not the president tries to impeach himself. It's all over the map -- raging from mounting a full defense, possibly led by Rudy Giuliani and even testifying himself to mounting no defense whatsoever. Simply declaring the impeachment is not legitimate. Jon Karl with us all week long. Jon, thank you.
