A city councilman in Sterling Heights, Michigan says he was questioned by the U.S. Secret Service after video emerged of him at a tea party rally holding signs that depicted violence against President Barack Obama, House Minority Leader Nancy Pelosi (D-CA) and former Michigan Gov. Jennifer Granholm (D).

The Sterling Heights City Council on Wednesday called for the resignation of Councilman Paul Smith after Mayor Pro Tem Michael Taylor discovered a YouTube video of him at a 2009 tea party rally holding signs that showed Obama’s head on a spike, Pelosi’s head riddled with bullet holes and Granholm’s head in noose. The resolution was passed 6-1, with Smith being the only “no” vote, according to The Detroit News.

In the video, Smith says the signs are to “show our governor, our president, Speaker of the House what we really think of them.”
