McConnell said the president's plan, which entails fixes to the Senate health care bill, is like "putting a new name on a whole lot more spending."
The administration believes that the best way to get a health care bill passed this year is to adjust what the Senate passed Christmas Eve. That bill won't require a Senate majority to pass.
Republican leaders want Obama and Democrats to scrap the bills altogether and start anew. The White House challenged the GOP Tuesday to post its health care bill. There are at least three different proposals put forward by various GOP lawmakers, including one by House Republicans.
"We've heard that they have ideas, and we look forward to those ideas," Senate Majority Leader Harry Reid, D-Nev., said Thursday. "The president did this because he wants to be able to reach out to the Republicans. That's who he is. He is not a partisan president. And I look forward to the meeting."
Senate Republicans will be represented Thursday by their leader, McConnell, the No. 2 two GOP senator, Jon Kyl, R-Ariz., two resident doctors and their 2008 presidential nominee Sen. John McCain, R-Ariz., among others. The list has not been set by House leaders of either party.
Meanwhile, Americans are not just unhappy with insurance companies or the Democrats' health care plans but also believe Republicans are not offering enough solutions.
Forty-nine percent of Americans disapproved of Democrats' health care plan, but 63 percent said lawmakers in Washington should keep trying to pass a comprehensive health care overhaul plan, rather than giving up on it, according to the latest ABC News-Washington Post poll.
Health care experts say both Democrats and Republicans need to meet halfway to achieve bipartisanship but on health care, it remains to be seen whether the White House summit will be any more than a public relations exercise.
