She's with him.
Hillary Clinton will endorse Joe Biden for president on Tuesday, according to a source familiar with the matter.
Clinton, who won the popular vote but lost the Electoral College vote in 2016 to Donald Trump, plans to announce the unsurprising endorsement during a virtual town hall event with Biden on Tuesday afternoon, the source told the New York Daily News.
The former secretary of state teased the endorsement over Twitter.
"A little hint about who the surprise guest will be for Joe Biden's 3pm ET town hall today," Clinton tweeted along with a photo of herself, Biden and former President Barack Obama in the Oval Office.
Making no bones about the endorsement, Biden responded to Clinton's tweet by referencing the failed Democratic presidential candidate's 2016 campaign slogan.
"(I'm with her). If you're exited too, join us at 3 PM ET," Biden tweeted along with a link to their virtual town hall event.
