Gaffney Tells Reagan "Your Father Would Be Ashamed Of You" (VIDEO)

Right-wing neoconservative Frank Gaffney went on "Hardball" Thursday night to defend Dick Cheney but ended up just insulting his fellow guest.

After a long exchange with Air America host Ron Reagan on the war in Afghanistan, Gaffney gave up on arguing and went for a personal attack. "Your father would be ashamed of you," he told Reagan, whose father was the late president.

"Oh, Frank," Reagan replied, "you better watch your mouth about that, Frank."

Watch the whole exchange:

Or just the insult:

In June, Gaffney wrote a column insisting that President Obama might really be a Muslim. In March, Gaffney argued that "evidence" exists connecting Saddam Hussein to 9/11, the 1993 attack on the World Trade Center, and the Oklahoma City bombing. Last September, Gaffney argued that Sarah Palin has learned foreign policy through "osmosis," by living in Alaska. He's argued that U.S. forces really did find weapons of mass destruction in Iraq, but the media covered it up. He's used made-up quotes and recommended "hanging" Democratic officials critical of the Bush administration's Iraq policy. He even believes there's "evidence" to support the "Birthers," and once recommended a military strike on Al Jazeera headquarters.
