Impeachment manager says he's not afraid of Trump running in 2024. He's afraid of him running, losing, and inciting another insurrection.

• Rep. Ted Lieu said if Trump ran in 2024 and lost, it could spark another violent insurrection.
• "I'm afraid he's going to run again and lose. Because he can do this again," Lieu said.
• Democrats hope to convict Trump in his Senate trial and bar him from running for office again.

Rep. Ted Lieu of California, an impeachment manager, on Thursday said he was not frightened of former President Donald Trump running for president again in 2024 - but scared of the consequences of another Trump loss.

In short, Lieu is worried that if Trump ran again and lost, it could result in another violent insurrection similar to Capitol attack on January 6.

"You know, I'm not afraid of Donald Trump running again in four years. I'm afraid he's going to run again and lose. Because he can do this again," Lieu said during the third day of Trump's Senate impeachment trial.

Typically, removal from office is the punishment for conviction in the Senate, though disqualification from holding office again is also a sanction that could be levied. Given that Trump is no longer in the White House, and removal isn't an option, Democrats are hoping to use the impeachment trial to prevent the former president from running again.

But Trump is expected to be acquitted, given the slim majority Democrats hold in the Senate.

With a two-thirds majority required for conviction, Democrats need 17 Republicans to join all 50 lawmakers in their caucus. In the unlikely event that Trump is convicted, a simple majority would be required to disqualify the former president from holding office again.

Trump is the third president in US history to be impeached - none have been convicted in the Senate. Only three people who've been impeached - former federal Judges West Humphreys, Robert Archbald, and Thomas Porteous - have been disqualified from future office.

On Thursday, impeachment managers laid out evidence that Trump embraced violence and extremism and his repeated baseless allegations about the election culminated in his supporters storming the US Capitol to impede the certification of President Joe Biden's win. Trump was also criticized for violence that took place at his 2016 campaign events.

Months after Election Day and weeks after Biden's inauguration, Trump has still not acknowledged that he lost the 2020 election. After the Capitol riot, Trump acknowledged Biden would be president. But Trump has not explicitly said he lost in a free and fair election.

The impeachment managers said Trump's baseless claims of mass voter fraud, general effort to overturn the 2020 election, and refusal to concede were at the heart of what caused the deadly violence at the Capitol on January 6. The riot occurred as Vice President Mike Pence and congressional lawmakers met to certify Biden's Electoral College victory. Five people, including a police officer, died.

Before the violence began, Trump delivered a speech near the White House in which he urged his supporters to "fight like hell" and march on the Capitol. He riled up his supporters, who then descended upon the Capitol. Some beat police officers and destroyed property. It was the most destructive, large-scale breach of the US Capitol since the War of 1812.
