By Jim Kuhnhenn, Associated Press - President Barack Obama is calling on Americans to rekindle the spirit of unity that characterized the country's response to the Sept. 11 terrorist attacks. "It can be a lasting virtue," he said. "Not just on one day, but every day."

The president made his appeal during his weekly radio and Internet address, two weeks before the 10th anniversary of the day al-Qaida terrorists turned commercial jetliners into deadly weapons in New York, Pennsylvania and northern Virginia.

Obama plans to observe the anniversary on Sept. 11 with stops at ground zero in lower Manhattan, where the World Trade Center towers fell; at Shanksville, Pa., where one of the commandeered planes crashed; and at the Pentagon, which was also hit by a hijacked jetliner.

But he cast his plea for good will on Saturday against the backdrop of the economic challenges facing the country today. Coming in the aftermath of bitter partisan fights over government spending and tough criticism of his administration by Republican presidential candidates, his remarks were an overt call for greater cooperation.

"Even the smallest act of service, the simplest act of kindness, is a way to honor those we lost, a way to reclaim that spirit of unity that followed 9/11," he said.

He recalled the work of volunteers following the attacks, the blood donations and the food and clothing drives.

"We were united, and the outpouring of generosity and compassion reminded us that in times of challenge, we Americans move forward together, as one people," he said.

These days, he said, the country is still fighting al-Qaida, it is ending the war in Iraq, pulling back troops from Afghanistan and "emerging from the worst economic crisis in our lifetimes."

"None of this will be easy," he said. "And it can't be the work of government alone. As we saw after 9/11, the strength of America has always been the character and compassion of our people.

"So as we mark this solemn anniversary, let's summon that spirit once more. And let's show that the sense of common purpose that we need in America doesn't have to be a fleeting moment; it can be a lasting virtue — not just on one day, but every day."

In the Republican address, Sen. Dean Heller of Nevada stuck to economic themes, criticizing the Obama administration for creating "more government that continues to impede economic growth at every turn."

"To paraphrase one of the business leaders in my state, this president and his policies have been a big wet blanket on our economy," he said.

Heller called for a balanced budget amendment to the Constitution and repeal of the health care law that Obama signed last year, both demands that Republicans have failed to achieve.

He also called for an overhaul of Social Security and Medicare to reduce their long-term costs and to simplify the tax code by eliminating loopholes and lowering tax rates.
