The Democratic National Committee launched a new ad this morning slamming New Jersey Gov. Chris Christie's "leadership," as the fallout from his administration's bridge scandal enters its second week.

The web video, shared exclusively with ABC News, is a brutal mash-up of some of Christie's least forgiving media coverage this weekend, starting with comments from fellow Republican Sen. John McCain of Arizona.

"He points out that he has 45,000, I think, employees although, obviously, these weren't average employees," McCain noted on CNN's "State of the Union" Sunday in an excerpt clipped for the ad.

Adds Republican strategist Kevin Madden: "One of the legitimate criticisms here is that every single organization is a reflection of its principle."

Christie fired deputy chief of staff Bridget Anne Kelly and cut ties with former campaign manager Bill Stepien last week after emails and text messages revealed their involvement in a ploy to close several lanes on the busy George Washington Bridge in an apparent act of political retribution.

Despite Christie's attempts to contain the controversy in a nearly two-hour news conference Thursday, media coverage continued well into the weekend.

The video is the second in the past week that the DNC has used tie Christie to the unfolding scandal and it highlights media coverage from major networks, including ABC News.

There's no evidence to disprove Christie's assertion that he played no part in the actions of his top aides, but Democrats have used the scandal as an indictment against Christie's leadership.

"With Bridgegate," the ad concludes, "the tone is set at the top."
