Michael Bloomberg, the former mayor of New York, will endorse Hillary Clinton for president at the Democratic National Convention, according to a spokesperson, the Associated Press reports. Bloomberg was elected mayor as a Republican.

Up until a few months ago there had been plenty of speculation that Bloomberg would run for president himself, as a third-party candidate. In March, Bloomberg decided against running, fearing it would benefit Donald Trump, the Republican presidential front-runner at the time, now the party’s nominee.

Senior advisor to Bloomberg, Howard Wolfson, commented on Bloomberg’s decision in the New York Times:

As the nation’s leading independent and a pragmatic business leader, Mike has supported candidates from both sides of the aisle. This week in Philadelphia he will make a strong case that the clear choice in this election is Hillary Clinton.

Bloomberg has not been a registered Democrat since 2000.
