Biden intervenes in Dem congressional primary, warning all 'we did to help ordinary people is in jeopardy now'

Former President Joe Biden has endorsed Dan Koh in the Massachusetts' 6th Congressional District Democratic primary, warning that their past efforts to help ordinary people are now in jeopardy. Biden's endorsement comes as Koh faces an open race with Rep. Seth Moulton running for U.S. Senate. Koh previously lost a 2018 Democratic congressional primary by a narrow margin.
