In response to a question by a reporter for The New York Post, Rep. Anthony Weiner (D-N.Y.) flatly said he would not resign his congressional seat.

"I'm not," Weiner said Thursday.

Weiner's comment comes as he faces increasing pressure from his own party to resign. Since Weiner admitted to sending a lewd photo to a woman in Seattle via his Twitter account and then lying about it, an increasing number of Democrats have called for him to resign. 

The National Republican Congressional Committee has pressured lawmakers to return money Weiner donated to House Democrats' campaigns. 

When Weiner acknowledged his behavior at a Monday press conference, he said he would not resign. 

On Wednesday, an X-rated photo, allegedly of Weiner, surfaced on a talk radio show visited by Andrew Breitbart, the conservative journalist who first broke the story.

House Minority Leader Nancy Pelosi (D-Calif.) has called for the House Ethics Committee to investigate Weiner.
