"It's a very simple plan," Grayson said in the speech Tuesday night. "Don't get sick. That's what the Republicans have in mind. And if you get sick America, the Republican health care plan is this: die quickly."
The after-hours speech, which included prominent banners behind the congressman to reinforce his point, drew immediate calls from some Republicans for an apology.
"That is about the most mean-spirited partisan statement that I've ever heard made on this floor, and I, for one, don't appreciate it," Tennessee Republican Rep. Jimmy Duncan told the Politico.
Grayson has not issued an apology, and a spokesman for the congressman said no additional statement on the matter is forthcoming.
Rep. Tom Price, R-Georgia, announced Wednesday he will introduce a resolution condemnig Grayson for the comments, similiar to a successful Democratic effort earlier this month that formally criticized South Carolina Republican congressman Joe Wilson for his "You lie!" outburst during President Obama's joint adress to Congress.
The National Republican Congressional Committee has already circulated several stories about the incident, eager to take aim at the freshman congressman from a swing district, who won by a 4 point margin in 2008.
The Democratic Congressional Campaign Committee is not responding to the comments.
