Former U.S. solicitor general and conservative stalwart Theodore Olson said the U.S. Senate has overwhelming evidence to convict former President Donald Trump at his impeachment trial on the charge of inciting a deadly insurrection at the U.S. Capitol last month.

The Senate should convict and disqualify Trump, Olson told The National Law Journal this week. What would a conviction take, Olson said, “if it isn’t encouraging, condoning and inciting an attempt at a violent overthrow of the government of the United States in the Capitol Building at a time when Congress is performing one of the most important constitutional responsibilities given to it?”
