Obama honors U.S. forces killed in helicopter attack

President Obama has arrived at Dover Air Force Base in Delaware Tuesday to pay tribute to 30 U.S. service members, including 22 Navy SEALs, killed in a helicopter crash in Afghanistan.

Obama led a delegation of administration and military officials to salute the remains of the fallen troops, whose helicopter was shot down by insurgents Saturday. It marked the highest single-day death toll for U.S. forces since the long war began a decade ago.

The scene has been closed to the public and the press, with Obama’s trip chronicled by a small group of pool reporters.

The remains were returned to Dover in “unidentified” status until they are positively indentified by the Armed Forces Mortuary Affairs Office.

Speculation mounted that Obama would head to Delaware after the White House canceled an event in Springfield, Va. to promote the administration new fuel efficiency standards for cars and light trucks. Instead, the president met with industry leaders at the White House on the topic.

The daily press briefing by Press Secretary Jay Carney was also canceled, meaning the White House likely will not show a public face a day after the president’s public remarks failed to stem the tide of losses from Wall Street on the first day of trading this week.

Monday, in what some Republican wags termed “The Obama Effect,” the Dow plunged another 200 points on its way to a 634-point drop after the president began speaking on the downgrade of the nation’s credit rating by Standard and Poor’s.

Wall Street rebounded Tuesday, with the Dow Jones Industial Average spiking more than 200 points.

Pressure has built on Obama to take some sort of dramatic action to send a signal that the U.S. is dealing with the global debt crisis, including recalling Congress from its August recess.

But Republicans on the Hill have shown little interest in striking any further deals with the president—and it remains possible that sustained gridlock could reinforce the view held by Standard and Poor’s that Washington is unable to come together to tackle the government’s most intractable spending issues.
