WASHINGTON — Day 4 of former President Donald Trump’s historic second impeachment trial is now underway.

The trial will force the Senate to decide whether to convict him of incitement of insurrection after a violent mob of his supporters laid siege to the U.S. Capitol on Jan. 6.

While Trump’s acquittal is expected, Democrats hope to gain at least some Senate Republican votes by linking Trump’s actions to a vivid description of the violence, which resulted in five deaths and sent lawmakers fleeing for safety.

The House impeached Trump on Jan. 13, one week later.

Trump’s lawyers say the trial should not be held at all because the former president is now a private citizen.

They argue that he did not incite the violence when he told his supporters to “fight like hell” to overturn his defeat.
