Sen. Bernie Sanders (I-Vt.) on Sunday backed new Maine Senate Democratic nominee Troy Jackson and said he will officially endorse the former state Senate president if Jackson "asks" him to. Jackson formally secured the Democratic nomination last weekend, winning 566 votes during a party convention in Bangor, Maine.

During Jackson's unsuccessful bid for the Democratic gubernatorial nomination in Maine, Sanders campaigned alongside him and Platner earlier this year. Our Revolution, the progressive organization Sanders founded after his 2016 presidential campaign but is not directly involved with, also backed Jackson during his bid for the Senate nomination this summer.
