Former Attorney General Eric Holder slammed the mindset of “Make America Great Again,” President Trump’s signature slogan, according to a report.

“This sort of thinking, this ‘Make America Great’ mindset is not only flawed, it’s rooted in fear. And it favors an imagined past over a realistic future,” Holder said while speaking at the Human Rights Campaign National Dinner late Saturday, according to The Hill.

Holder — who has said he is considering a run for president in 2020 — also asked what time period those who want to “make America great again” would rewind to if given the opportunity.

“Certainly it was not when people were enslaved,” he said. “Certainly it was not when segregation was the law of the land. Certainly, it was not when women were disenfranchised. Certainly, it was not when the LGBT community was routinely stigmatized.”

Holder, who served as AG from 2009 to 2015 under President Barack Obama, currently runs the National Democratic Redistricting Committee, which encourages pro-Democratic redrawings of congressional districts.

On Saturday, he also encouraged people to vote in the midterm elections.

“We have an opportunity to send a message … to the present occupant of the White House, to the extremists who surround him and to those that support him, that we will not allow for the dismantling of the social compact forced by Roosevelt and other great presidents between we the people and our government,” he said.

“Make no mistake, we are in the struggle of our lives.”
