President Joe Biden said Donald Trump’s “phony populism” had hurt the former GOP president’s political party and left Senate Republicans reluctant to back a Jan. 6 commission to investigate the Capitol riot.

“The Republican Party is vastly diminished in numbers … [its] leadership … fractured. And the Trump wing of the party is the bulk of the party, but it makes up a significant minority of the American people,” Biden told reporters during a press conference in Belgium, adding that he “didn’t want to get into the statistics.”
