"There is no Republican Party. There's a Trump party. The Republican Party is kind of taking a nap somewhere," he said at the Mackinac Policy Conference in Michigan.
Boehner, of Ohio, also described his relationship with Trump, saying that Trump would call him when he was speaker but that neither thought Trump would win the 2016 election.
"Donald Trump, who I know well, was one of my supporters, when I was speaker," Boehner recalled. "I was having a rough week, Trump would call me, pat me on the back, cheer me up, played a lot of golf together. But president? Really? I never quite saw this."
