President Obama's carefully written remarks on the fate of the Guantanamo Bay prison hit a major snag Thursday -- a loud and insistent protester.
Medea Benjamin, co-founder of the antiwar group known as Code Pink, continually interrupted Obama as he talked about steps to close Gitmo, arguing that it should have been done already.
"Let me finish," Obama said at one point.
As Benjamin continued to talk -- and was eventually escorted from the hall -- Obama said her words and those of other protesters have to be taken seriously.
"These are tough issues," Obama said.
