BOSTON (AP) — Republican U.S. Senate hopeful Gabriel Gomez is planning to release the first television ad of his campaign against Democrat Edward Markey.

Gomez introduces himself in Spanish in the 30-second ad and talks about the goal he had growing up of serving his parent's adopted country by becoming a Navy SEAL.

The ad is paid for by the Massachusetts Republican Party.

It comes after Markey released a new ad Thursday criticizing Gomez for opposing reinstatement of a federal assault weapons ban and a ban on high capacity magazines "like the ones used in the Newtown school shooting."

Gomez campaign officials don't dispute the ad's substance, but say it shows Markey wants to avoid talking about jobs, the economy and national security.

The June 25 election is to fill the seat left vacant by U.S. Secretary of State John Kerry.
