MSNBC host and civil rights activist Al Sharpton said in a new interview he won’t rule out a run for president in 2020, adding he isn’t currently mounting a bid.

“I never rule anything out,” Sharpton told BuzzFeed News.

The progressive firebrand and outspoken critic of President Donald Trump ran for the Democratic presidential nomination in 2004, although it was viewed as more of a stunt than a serious attempt at the White House. He also ran previously for U.S. Senate and New York mayor.

Sharpton was a strong ally of President Barack Obama and said he would never use his MSNBC platform to criticize his administration. Sharpton, who has known Trump for decades as a fellow fixture of New York, has blasted him as racist.
