WASHINGTON (AP) - President Barack Obama signs the landmark health care bill in the White House East Room Tuesday.
His spokesman says Obama is inviting all of the lawmakers who supported the bill, along with other Americans whose stories represent the need for health care reform.
Later in the week, Obama will be traveling to Iowa, as he starts talking-up the benefits of the bill on behalf of House members who cast risky votes.
And he still has to see a companion bill through the Senate.
As House Speaker Nancy Pelosi signed the legislation today -- a formality before Obama's own signature -- she said the House had "made history." Pelosi says the legislation is "on a par with passing Social Security and Medicare."
Debate is expected to begin as soon as tomorrow in the Senate on a companion measure making a series of changes sought by House Democrats.
Republicans plan parliamentary objections that could change the bill and make it go back to the House.
