Jeff Flake, the former senator from Arizona, doesn't know whether he would have voted to impeach President Trump, but is sure of one thing: Trump definitely did something wrong.

Flake announced in 2017 he would not seek re-election, saying he felt there wasn't any room in the Republican Party for critics of Trump. He was in the Senate chamber on Tuesday, watching his former colleagues participate in Trump's impeachment trial, and during a break told reporters he saw valid points on both sides of the argument over whether Trump's pressure on Ukrainian President Volodymyr Zelensky was an impeachable offense.

Trump pushed Zelensky to launch an investigation into his political rival, former Vice President Joe Biden, and while Flake doesn't know if Trump should be removed from office over this, it wasn't a good idea. "As a Republican, it pains me when I see Republicans, House Republicans, try to maintain that the president did no wrong, that this is somehow normal," he said. "It's not." Catherine Garcia
