Two Republicans took the stage at the Democratic National Convention Thursday to announce they would be voting for Democrats for the first time: Doug Elmets, formerly a speechwriter for President Reagan, and Jennifer Pierotti Lim, co-founder of Republican Women for Hillary.

“I knew Ronald Reagan. I worked for Ronald Reagan. Donald Trump: You are no Ronald Reagan,” Elmets said to cheers. He proceeded to criticize Trump’s proposal to build a wall along the Mexican border, citing Reagan’s famous “Tear down this wall” speech.
