A mysterious new website has popped up accusing billionaire entrepreneur Elon Musk of cronyism and inappropriate ties to top political leaders. But who, exactly, is behind the site remains unclear, as its sponsors have taken steps to hide their identities.

The focal point of WhoIsElonMusk.com is a slickly produced video, posted just days ago, that slams Musk as an “American Swindler” and a “foreign-born” businessman who got rich off U.S. tax dollars.

Musk has made his share of enemies in Washington, as his businesses have put him on a collision course with corporate behemoths like General Motors, Ford Motor Company, Boeing and Lockheed Martin.

Musk is the founder of electric car company Tesla, space launch company Space Exploration Technologies Corp. and chairman of the solar energy company, Solar City.

An ominous voiceover in the video accuses Musk of “lining the pockets of Democratic and Republican politicians with millions of dollars in donations … but fleeced the American taxpayer.” President Barack Obama, Sen. John McCain (R-Ariz.), Sen. Chuck Schumer (D-N.Y.) and House Majority Leader Kevin McCarthy (R-Calif.) all make cameos. According to FEC documents, Musk has donated about $500,000 to various political campaigns over the last decade.

Solar City and Tesla have received tax credits as clean energy companies, and SpaceX receives government contracts to carry out space launch missions.

The activity on the web site comes as Musk's SpaceX helped shine a light on a Boeing-Lockheed joint venture known as the United Launch Alliance, which for years had a monopoly on the Pentagon's space launch business until SpaceX sued for the right to compete. POLITICO reported this month that SpaceX has promised to launch government wares for a much lower price than ULA and has been supported in its efforts by McCain, who has accused ULA and its congressional allies of “corruption.” A representative for SpaceX declined to comment.

The website appears to have been designed by Orange Hat, an Alexandria-based firm. The firm promises to “utilize the most effective digital resources to engage and mobilize your target audience and drive measurable results.” Keith Cowing, of the blog NASA Watch, first uncovered the connection to Orange Hat.

Randy Skoglund, Orange Hat’s managing partner, declined to comment on the anti-Musk website when contacted by phone Wednesday, and then hung up. Brad Summey, the firm’s chief Technology officer, did not respond to requests for comment.

The website was largely dormant until recently. There were only four blog posts on the site during all of 2013, 2014 and 2015, but that changed in recent weeks. Since February 2016, the site has added 22 posts.

The website says it is a product of the Center for Business and Responsible Government, “a non-partisan organization dedicated to highlighting cronyism and its effect on American taxpayers and policy.” There is virtually no information to be found online about the center; it does not have a website and does not come up in a search of corporate registrations and other public documents.
