WASHINGTON (CNN) - Iowa Republican Sen. Charles Grassley - one of the Republican members of the Senate Finance Committee's "Gang of Six" - told reporters Thursday it's been six weeks since he's spoken to President Obama or anyone on the White House staff.
"I'll tell ya, there's some things that the president has said since then, that I took very personally," Grassley said.
The Iowa senator said he took offense to comments made by the president last month in response to a controversy of a provision regarding end-of-life counseling in one of the health care reform bills in the House.
"You have every right to fear," Grassley told constituents at a town hall in mid-August, "You shouldn't have counseling at the end of life, you should have done that 20 years before. [We] Should not have a government run plan to decide when to pull the plug on grandma."
At a health care event of his own last month, the president responded to similar criticism.
"The notion that somehow I ran for public office or members of Congress are in this so that they can go around pulling the plug on grandma ... when you start making arguments like that, it's simply dishonest," Obama said.
The presidential comeback still doesn't sit well with Grassley. The senator said he resents accusations that he and other Republicans have been more concerned with scoring political points than achieving a consensus on policy in the debate over health care reform.
"I kinda resent – when I have been very candid with the President of the United States, face-to-face . . . And I leveled with him . . . And then we're accused by Axelrod of making political things and maybe not being serious in our negotiations," Grassley told reporters Thursday. "That's not a very good environment to carry on a conversation with the White House."
Grassley also suggested Thursday that it was "intellectually dishonest" to call the proposal unveiled by Senate Finance Committee Chairman Max Baucus, D-Montana, a bipartisan bill.
For several weeks, Baucus and Grassley have been working with two Republicans and two Democrats – known as the "Gang of Six" – in trying to strike a compromise that might win broad support in the Senate. Grassley and fellow Republican Sens. Mike Enzi and Olympia Snowe are not supporting the Baucus proposal that is set for mark-up in the Finance Committee. But the three Republicans have said they remain committed to crafting a bill that will garner bipartisan support.
