Washington (CNN) - President Barack Obama is postponing a trip to Indonesia and Australia to remain in Washington for the expected House vote on the health care bill, a spokesman said Thursday.
White House spokesman Robert Gibbs said Obama is likely to make the visit in June. The president had been scheduled to leave for the trip Sunday.
The House of Representatives is expected to vote this weekend on the health care bill passed by the Senate in December.
"The president greatly regrets the delay. ... The passage of health insurance reform is of paramount importance, and the president is determined to see this battle through," Gibbs said.
Obama believes the measure will pass, Gibbs added.
Gibbs also announced a state dinner for Mexican President Felipe Calderon on May 19.
