Bernie Sanders’ Secret Service protection has ended, Fox News confirms.

The decision comes after the Democratic presidential candidate formally endorsed presumptive nominee Hillary Clinton on Tuesday. According to a Secret Service source, his protection ended at 5:30 p.m. that day.

Sanders hasn’t technically dropped out, however. Asked if the campaign is over, spokesman Michael Briggs told Fox News:

"His name will be placed in nomination in Philadelphia. Just like her in 2008. So no, the campaign is not over."
