Cohasset businessman Gabriel Gomez has formally launched his U.S. Senate bid.

The Republican and former Navy SEAL made the official announcement today in Quincy, two weeks after releasing a video saying he was running.

Gomez is proposing a lifetime ban on lobbying by former members of Congress and term limits for the House and Senate to phase out what he called "career politicians."

He was scheduled to make appearances later today in Shrewsbury and West Springfield.

Former Lt. Gov. Kerry Healey appeared at Gomez's kickoff event.

Gomez, Norfolk state Rep. Daniel Winslow and former U.S. Attorney Michael Sullivan all say they've collected enough signatures to get on the April 30 Republican primary ballot.

Edward Markey and Stephen Lynch are facing off against each other on the Democratic side.
