President Barack Obama, in his first appearance since sweeping Republican victories in the midterm election, said that Americans sent a clear message: "They want us to get the job done." "To everyone who voted, I want you to know I hear you," Obama said Wednesday. "To the two-thirds of voters that chose not to participate in the process yesterday, I hear you too." Obama called on Congress to pass comprehensive immigration reform and raised the prospect of taking action on his own. He also said he was open to changes in his signature health care law, but said he would not support eliminating its mandate that people buy insurance coverage.
