Ammon News - (Reuters) - President Barack Obama on Wednesday scrapped part of long-planned trip to Asia and left the remainder of the trip in doubt as a U.S. government shutdown entered a second day with no end in sight to the funding battle in Congress that triggered it.

Obama scuttled two stops on a planned four-country tour and left visits to two other countries up in the air, according to White House statements.

The president told his counterparts in Malaysia and the Philippines he would not be able to meet them as planned and a White House official said the president is weighing whether to attend diplomatic summits in Indonesia and Brunei.

"We will continue to evaluate those trips based on how events develop throughout the course of the week," National Security Council spokeswoman Caitlin Hayden said.

Obama was originally due to leave the United States on Saturday and return a week later.

Not only must the president deal with the budget impasse and its effects, but he faces an even bigger crunch in Congress, which will put the United States at risk of defaulting on its debts if it does not raise the U.S. public debt ceiling. Treasury Secretary Jack Lew has said the United States will exhaust its borrowing authority no later than October 17.

The fight between Obama's Democrats and the Republicans over the government's borrowing power is rapidly merging with the standoff over every day funding, which has forced the first government shutdown in 17 years and forced hundreds of thousands of federal employees to take unpaid leave.

The White House announcements about the Asia trip followed a fruitless day on Capitol Hill, with congressional Democrats and Republicans coming no closer to resolving their differences.

Obama accused Republicans of taking the government hostage to sabotage his signature healthcare law, the most ambitious U.S. social program in five decades, passed three years ago.

Republicans in the House of Representatives view the Affordable Care Act as a dangerous extension of government power, and have coupled their efforts to undermine it with continued efforts to block government funding. The Democratic-controlled Senate has repeatedly rejected those efforts.

The standoff has raised new concerns about Congress's ability to perform its most basic duties and threatens to hamper a still fragile economic recovery.

"This is a mess. A royal screw-up," said Democratic Representative Louise Slaughter of New York.

LANDMARKS CORDONED OFF

As police cordoned off landmarks such as the Lincoln Memorial, and government agencies stopped functions ranging from cancer treatments to trade negotiations, Republicans in the House sought to restore funding to national parks, veterans' care and the District of Columbia, the capital.

An effort to pass the three bills fell short on Tuesday evening, but Republicans plan to try again on Wednesday. They are likely to be defeated by the Democratic-controlled Senate.
