President Obama will sign an expansion of the State Children's Health Insurance Program (SCHIP) today at 4:30 p.m., according to the White House, enacting legislation that has been a top priority for congressional Democrats since the 110th Congress.

The House passed an SCHIP extension today 290-135, sending it to Obama's desk. The bill reauthorizes SCHIP for the next four and a half years at higher funding levels.

The House passed a previous $35 billion expansion in 2007, which President Bush vetoed. Democratic leaders tried and failed to override the veto in October of that year.
