(CNN) -- As President Obama begins his vacation in Martha's Vineyard this week, the fiery debate over health care reform continues to rage.
The latest member of congress to wade into the issue is California Rep. Maxine Waters, a liberal Democrat who at a town hall over the weekend implored the president not to drop the public option plan and said his efforts at bipartisanship are futile.
"Yes, we know that you are a nice man, that you want to work with the opposite side of the aisle. But there comes a time when you need to drop that and move forward," she said. "We're saying to you, Mr. President, 'Be tough. Use everything that you've got. Do what you have to do. And we have your back.' "
The longtime congresswoman, whose district includes much of Los Angeles, also described some senators who are opposed to the health care reform bill as "Neanderthals."

"Not only are we going to do everything we can to organize and put pressure on the senators - some of whom are Neanderthals - we're going to say to the president, 'We want you to use every weapon in your basket in order to get those senators to do what they should be doing,' " she said.
The comments were met with strong applause in the forum held at L.A. Southwest College, a community college that that abuts several impoverished neighborhoods.
