Massachusetts Sen. Elizabeth Warren, a potential running mate for Hillary Clinton, met with the presumptive Democratic nominee Friday – as the Clinton campaign confirmed she held several meetings about her vice-presidential selection process.

Warren, frequently touted as a pick who would help bring disenfranchised Bernie Sanders supporters on board, met Clinton for about an hour, Fox News learned. Warren endorsed Clinton last month.

"On Friday, Secretary Clinton held a series of campaign-related meetings at her Washington home, including several about her vice presidential selection process,” campaign spokesman Brian Fallon said.

Warren was omitted Friday from the list of candidates set to speak at the upcoming Democratic convention in Philadelphia. Fox News was previously told she was set to speak on July 25, the same day as Sanders is slated to speak.

Colorado Gov. John Hickenlooper and Housing and Urban Development Secretary Julian Castro also met with Clinton, the Associated Press reported.

The meetings came as presumptive Republican nominee Donald Trump announced Indiana Gov. Mike Pence as his running mate.
