Former Sen. Joe Lieberman announced Wednesday he will vote for former Secretary of State Hillary Clinton, citing her work in the Senate and ability to work across party lines as the main reason.

Lieberman, an independent Democrat and 2000 Democratic vice presidential nominee, told Fox Business host Maria Bartiromo, also noting his history with the former New York senator, as well as former President Bill Clinton, dating back to their time at Yale Law School. He also said that he hadn’t waded into the 2016 conversation because of his work for No Labels, an independent group that pushes members of Congress to cross party lines to pass legislation.
