Cory Booker is launching his first TV ad as a Senate candidate -- an ad that plays up his accomplishments as mayor of Newark.

The ad, titled run, begins Wednesday and features the mayor speaking directly to camera, arguing that he has made progress on issues like guns, education and business.

"I've proven that by bringing people together even with big problems, we can make big progress and improve people's lives," Booker (D) says in the ad.

Booker's record as mayor has received some scrutiny, most notably by the New York Times. It seems likely to be a line of attack used against Booker, who is a heavy favorite to succeed the late Sen. Frank Lautenberg (D-N.J.).

The ad is part of a reported $400,000-plus ad buy.

The special election is set for Oct. 13, with the primary Aug. 16.
