Iowa Congressman Bruce Braley, a Democrat from Waterloo, says there’s a good chance the U.S. House will be able to override the president’s veto of a bill that would expand the number of children covered by government-paid health care. The bill is called the State Children’s Health Insurance Program , or “S-CHIP.”

Braley says the latest information he has on a possible veto override is that it may not happen immediately, as there are a lot of interest groups trying to apply pressure to House Republicans who voted against the bill. Braley says they numbers for an override are pretty easy to figure out. He says there were 265 votes in favor of the bill, so they need 24 additional votes to override.

Braley says nine of the no votes were Democrats, and he his confident they will vote to override, so they need 15 additional Republican votes to override the veto. Braley says it may take some time to line up the votes.

Braley says based on the information they have today, an override attempt could happen next week or the week after, but there’s no definite timeline. Republican Steve King, was the only member of the Iowa House delegation to vote against the S-CHIP bill.
