WASHINGTON — President Barack Obama plans to sign the main health care overhaul bill Tuesday in a White House ceremony.
He'll deliver remarks on his signature domestic priority and plans further comment on health care at the Interior Department after the signing.
Later, Obama meets with two senators to discuss the START nuclear arms reduction process. He will also have a closed-door session with Israeli Prime Minister Benjamin Netanyahu (neh-ten-YAH'-hoo).

The House of Representatives passed the health care reform bill Sunday night with a 219-to-212 vote. With the Senate already having passed the bill on Christmas Eve, it now stands ready for President Obama to sign into law, perhaps as early as Tuesday.
Many challenges remain, though. Attorneys general in 12 states have said they will challenge the constitutionality of the health care bill. Moreover, Democrats still want to make changes to the final bill after the fact.
The House has already passed this package of fixes – which would rein in some of the special deals made with senators last year. Now the Senate must pass the same package of fixes before Mr. Obama can sign them into law. To do that, the Senate will have to turn to the contentious and time-consuming process of reconciliation.
But the outlines of the bill are now clear. Here is the Monitor's comprehensive look at what is in the health care bill and how it might affect you.
