Yes, I will take credit, or blame really, for Grover Norquist. He was one of the many conservatives — Ann Coulter, Laura Ingraham — lots of people who we introduced to the American public back in the 90’s on Politically Incorrect, when we needed foils for me. I guess they’re getting the last laugh since they’re actually controlling America now.

The offices of Americans for Tax Reform, the anti-tax group run by conservative activist Grover Norquist, were evacuated Monday morning after a bomb threat.

Norquist’s office contacted the Washington Metropolitan Police Department around 9 a.m. on Monday after the bomb threat was called into the ATR office, according to The Hill.

Anthony Clay, a police spokesperson, told Politico that a bomb unit searched the office and found no explosives.

"The police are conducting an investigation," John Kartch, director of communications for Americans for Tax Reform, wrote in an email to The Hill.
