Bernie Sanders will hit the trail for Hillary Clinton on Monday in New Hampshire, in the former Democratic presidential rival's first event campaigning solo since he announced his endorsement of the former secretary of state in July.

"Sanders will discuss Hillary Clinton's plan to building [sic] an economy that works for everyone, not just those at the top, and Donald Trump's plan, which would benefit himself and other millionaires and billionaires," the Clinton campaign said in an announcement.


The Labor Day event is set for 3 p.m. at a high school in Lebanon, New Hampshire.
