Former Secretary of State John Kerry said on Sunday that he will not be running for president, denying a recent report saying he was considering running in 2020 and calling it “categorically false.”

“As I told the reporter, I am absolutely not running for President. Any report otherwise is categorically false,” he said on Twitter. “I’ve been proud to campaign with my good friend Joe Biden, who is going to win the nomination, beat Trump, and make an outstanding president.”

In an earlier tweet that has since been deleted, Kerry shared similar sentiments using profanity. 

It was reported by NBC News on Sunday that one of their analysts reported that they overheard Kerry talking on the phone about running for president in a Des Moines, Iowa hotel. The report also mentioned that Kerry had talked about having to give up being paid to deliver speeches and having to step down from his position on the board of Bank of America.

The former Secretary of State and 2004 presidential nominee endorsed former Vice President Joe Biden in December, saying he’s the only candidate that has the character and leadership skills to beat President Donald Trump.

“I believe Joe Biden is the President our country desperately needs right now, not because I’ve known Joe so long, but because I know Joe so well,” Kerry said at the time.
