Rep. Vicky Hartzler (R-Mo) became the latest Republican to express uncertainty over President Barack Obama's citizenship this week at a town hall event with her constituents.

A group called Show Me Progress filmed Hartzler's response to a question about the authenticity of Obama's birth certificate.

"You know, I have a lot of doubts about all that," Hartzler said. "But I don't know, I haven't seen it. I'm just at the same place you are on that. You read this, you read that. But I don't understand why he didn't show that right away. I mean, if someone asked for my birth certificate, I'd get my baby book and hand it out and say 'Here it is,' so I don't know."

Hartzler reportedly continued to express her skepticism over Obama's birth certificate in an interview after the town hall.

“You know I have a lot of doubts about all that,” she said. “I don’t understand why he didn’t show that right away.”
