Former Attorney General Eric Holder and Vice President Mike Pence are have found themselves in a twitter beef this week.

Huff Post reports, that the two got into a spat over President Donald Trump‘s campaign slogan “Make America Great Again”. Holder stirred the pot on Wednesday when he told MSNBC‘S Ari Melber that the “notion of greatness” that President Trump’s “Make America Great Again” campaign slogan  “never in fact really existed.”

“When I hear these things about let’s ‘Make America Great Again,’ I think to myself, exactly when did you think America was great?” Holder asked. “It certainly wasn’t when people were enslaved. It certainly wasn’t when women didn’t have the right to vote. It certainly wasn’t when the LGBT community was denied the rights to which it was entitled.”

“You know, America has done superb things, has done great things, and it has been a leader in a whole range of things, but we’re always a work in process,” he added. “Looking back, ‘Make America Great Again’ is inconsistent with who we are as Americans at our best where we look at the uncertain future, embrace it, and make it our own.”

After Holder’s comments, Pence took to Twitter Thursday with photos of American and one simple question to defend the President’s slogan as second-in-command. “Exactly when do you think America was great,” he questioned.

Holder responded and said “America IS great” and “can-and must-be greater still” and the “Make America Great Again” slogan means, “YOU think America is not great now-and is backward looking. America is at its best when we look forward, embrace an uncertain future and make it ours. That is what defines American greatness.”

But Holder isn’t alone, according to Fox News, politicians like New York governor, Andrew Cuomo, questioned last year was American ever really great, “We have not reached greatness, we will reach greatness when every American is fully engaged, we will reach greatness when discrimination and stereotyping against women, 51 percent of our population, is gone,” he said.
