DENVER -- President Barack Obama will be in Denver today to sign the $787 billion economic stimulus package into law.

The legislation is made up of infrastructure spending and tax credits and will give millions of workers $13 extra each paycheck starting in June.

Individuals could get up to $400 and $800 for couples.

First-time home buyers who purchase their homes before Dec. 1 would be eligible for an $8,000 tax credit. And those receiving unemployment benefits this year wouldn't pay any federal income taxes on the first $2,400 they receive.

Details Of Obama's Visit

Obama will be speaking at the Denver Museum of Nature and Science at about noon. He will arrive at Buckley Air Force base and either take a motorcade or use Marine One to fly to City Park.

Traffic is expected to be impacted, especially around the museum and City Park.

Obama's signing ceremony is by invitation only. The museum closes to the public today for the occasion.

Passes for the visit contain an image of the White House and presidential seal, but they are upside down, according to 7NEWS reporter Russell Haythorne. That will likely make them even more valuable as collector's items.

Today's visit will be Obama's first to Colorado as president, though he stumped here frequently as a candidate. Obama was last in Colorado on Nov. 1, the Saturday before Election Day, when he addressed a rally in Pueblo.

Museum director George Sparks said that Obama's ceremony will be the first time a sitting president has visited the institution.

He is expected to tour the solar panels on the roof of the museum.

Colorado's 'Green' Focus Makes State Perfect Venue, Gov Says

Gov. Bill Ritter believes that the president picked the Mile High City as the place to sign the stimulus because of our state's potential for renewable energy jobs.

Ritter said Colorado is the "perfect venue" for signing of the stimulus bill because the bill includes investments in renewable energy sources being developed in Colorado, including wind and solar energy.

"Colorado, because of the work that we've done in creating new energy economy and being able to create sustainable job growth, provided this template for the administration to say 'This is what the package is about,"' Ritter told reporters outside the museum Sunday.

"I'd have to say that has everything to do with why it's being signed here."

Colorado stands to receive more than $130 million for clean energy and weatherization assistance programs under the plan, the Rocky Mountain News reported.

Coming with Obama to Colorado will be Interior Secretary Ken Salazar, who left the Senate to join Obama's Cabinet. The Denver Post reported Sunday that Salazar would come on the president's plane.

Salazar told the newspaper through a spokesman Saturday that Obama "couldn't have picked a better place to highlight how the bill will create jobs and build the type of clean-energy economy that is already growing in Colorado."

Obama To Address Housing Crisis In Phoenix

After Obama signs the bill into law in Denver, his western tour continues to Arizona. Obama planned to shift to the housing crisis with an announcement Wednesday in Phoenix, an announcement expected to concern plans to help homeowners facing foreclosure.

Late last summer, Americans began feeling the pinch of the recession and left the housing market in huge numbers. That coincided with a sharp increase defaults on home mortgages, a devastating combination that triggered the financial crisis. Lending froze as banks and investment houses realized they were holding trillions of dollars in bad assets.

Obama's staffers said the president wants to continue taking his economic message to the American people, who are giving him high marks for handling the crisis.

"He is determined to keep in touch with the American people who sent him here to do this job," senior adviser David Axelrod said

"This (the stimulus bill) was was created not for the sake of Washington, not for the sake of the Obama administration," Ritter said. "This was because people out in the states have been saying we need help, and we really need help around job creation."
