MGM Resorts, the biggest employer and casino operator on Las Vegas Boulevard, this month added $250,000 to the $50,000 already given to Patriot Majority PAC, Bloomberg reports. The group has been running television ads in support of Reid.

Earlier today, MGM CEO Jim Murren told CNBC the story about how Reid saved the $8.5 billion CityCenter mega-complex by convincing banks to return Murren’s calls, which led to loans that staved off bankruptcy.

Murren also went on CNBC Friday morning to slam Angle, saying he’s “going to be a very worried executive” if she wins, and that Angle has “a lack of basic business understanding that’s frightening to me.”

The Reid campaign is famous for this kind of carefully coordinated messaging, which this week featured several Nevada business and community leaders coming out against Sharron Angle in a new television ad.

Former Las Vegas mayor and Senior Vice President of Communications for Harrah’s, Jan Jones, said that “electing Sharron Angle would cost thousands of jobs.”

“She will be the knockout punch for Nevada’s economy,” said Senior Managing Director of Southern Wine & Spirits Larry Ruvo in the ad. “We need the majority leader.”

Last month, Palms owner George Maloof also endorsed Reid.
