Former Attorney General Eric Holder could be preparing for a presidential run, according to an MSNBC analyst.

Eugene Robinson tweeted Thursday evening that he heard “from a good source that Eric Holder has been consulting strategists about possibly jumping into the Dem presidential primary.”

Reports of a potential Holder candidacy in 2020 came shortly after the New York Times and other outlets reported that billionaire Michael Bloomberg was readying paperwork to enter the Alabama presidential primary.

MSNBC’s Rachel Maddow cited Robinson’s tweet as she discussed the possibility of a Holder run.

“I will just mention that our Pulitzer Prize-winning colleague Eugene Robinson reported online tonight that … former Attorney general Eric Holder has been talking to strategists about whether he ought to get in the race as well,” Maddow said.

She added, “But if Eric Holder is potentially in the mix and Mike Bloomberg looks like he might be in the mix, well, jeez, just when you thought it’s all over, it’s never over.”

Holder, who held office during the Obama administration and was the first African American attorney general, ruled out a bid for the presidency in March this year.

In an op-ed published by the Washington Post, Holder said that he would “not run for president in 2020” and instead focus on his work fighting gerrymandering with the National Democratic Redistricting Committee.

“I will do everything I can to ensure that the next Democratic president is not hobbled by a House of Representatives pulled to the extremes by members from gerrymandered districts,” Holder wrote.
