Bernie Sanders will campaign with Hillary Clinton in Portsmouth, New Hampshire, the Vermont senator announced Monday.

“U.S. Sen. Bernie Sanders on Tuesday will join Hillary Clinton for a campaign event at Portsmouth High School to discuss their commitment to building an America that is stronger together and an economy that works for everyone, not just those at the top,” the Sanders campaign said.

The Clinton campaign released an identical statement.

Sanders and Clinton were the chief rivals for the Democratic presidential nomination this year, with the 74-year-old socialist putting on a stronger-than-expected showing.

Clinton is set to become the official Democratic nominee later this month at her party’s convention in Philadelphia from July 25 to 28.
