CAMBRIDGE, MA(TIP): Indian American Shiva Ayyadurai, who is running for the US Senate from Massachusetts, has sued Cambridge city officials for sending him a notice to remove his campaign signs that called his Democratic opponent Sen. Elizabeth Warren a “fake Indian.”

Ayyadurai is a staunch critic of the incumbent senator, has been attacking Warren for claiming Native American ancestry. He and GOP critics of Warren say the senator lied about her Native American heritage for securing jobs, including one as a Harvard law professor. Claiming that he is a real Indian from India, Ayyadurai terms Warren as a “fake Indian.”

On April 22^nd, he filed a suit against the City of Cambridge alleging that by asking him to take down the signage, the city is encroaching upon his constitutional right to free speech.

Ayyadurai has a campaign bus with photos of himself and Warren with words juxtaposed saying “Only a REAL Indian Can Defeat the Fake Indian.”

According to reports, the vehicle has been stationed for more than a month next to a building owned by Ayyadurai which also happens to be in the neighborhood of Warren.

The Cambridge building inspector Branden Vigneault had earlier this month issued Ayyadurai a notice asking him to remove the inappropriate signage from the vicinity as it lacked prior “approvals and permits.”

The Ayyadurai campaign said that the building inspector threatened to fine $300 per day and additional legal proceedings if the signs are not removed within a stipulated period.

“We will not remove the slogan from our bus,” Ayyadurai told The Washington Times. “We will defend the First Amendment, and we will fight this egregious attack on the First Amendment, at any cost.”

His campaign managers have told the media that building regulations don’t apply to the current circumstance as the signage is on a bus.
