Former Senator Joe Lieberman dropped out of the running for FBI director, according to multiple news reports.

Lieberman, who represented Connecticut in the Senate as a Democrat and is now an independent, was believed to be the frontrunner for the nation’s top law enforcement job.

One potential complication — the Washington Post reported Tuesday that Mr. Trump hired Marc Kasowitz as his private attorney to deal with the federal investigation into Russia’s interference in the 2016 U.S. election, and Lieberman has been working as a senior counsel at Kasowitz’s law firm for several years.
