President Obama signed the health care reform bill on Tuesday, marking the completion of one of his top presidential priorities, CNN said.
The bill is the largest piece of social legislation passed in the last 40 years, yet Republicans and social conservatives are already planning attempts to repeal the bill, CNN said.
The signing took place in the East Room of the White House. Members of Congress, supporters, and ordinary citizens who have experienced hard times under the health care laws crowded the room, Associated Press said.
Obama will make a trip to Iowa on Thursday to talk about the reform, Associated Press said.
