U.S. Sen. Ed Markey could be facing yet another primary challenger — Rep. Joe Kennedy III.
Kennedy is reportedly considering taking on Markey. If he does, he would be the third person to challenge the longest-serving member of the Massachusetts congressional delegation.
Markey has declined to comment on his primary challengers, but has said he's running for re-election no matter what.
