Today marks one year since President Barack Obama was elected as the nation’s first African-American President. We want to know your thoughts on the last year.

Post your comments and Heidi will read some of them in the Newsroom, from 9am to 11am ET.

One year after he won a historical presidential election, 54% of Americans approve of the job Barack Obama's doing in the White House. Of those questioned in the CNN/Opinion Research Corporation survey released today, 45% say they disapprove.

The survey suggests the president's overall approval rating remains above 50% even though a majority of Americans disapprove of how he is handling the economy, health care, Afghanistan, Iraq, unemployment, illegal immigration and the federal budget deficit.

We want to hear from you. How do you think the President is doing one year later?

Executives of the nation's biggest bailed-out companies are about to get dramatic pay cuts. The Obama administration's pay czar wants their salaries cut in half.

An administration official tells CNN that Kenneth Feinberg, who was named the White House's pay czar in June, will demand that each of the seven largest bailout recipients cut the total compensation for their top 25 highest paid employees by 50%, on average. Under the plan, annual salaries for executives could fall 90% on average.

What do you think? Is the administration’s plan more unnecessary government intervention in the private sector or justifiable regulation when corporations are subsidized by the federal government?

Many feared 6-year-old Falcon Heene had stowed away in a runaway Mylar balloon that was speeding across the Colorado sky yesterday. He was later found hiding in his family's attic.

In an interview with CNN's "Larry King Live," Falcon said he heard his parents call for him from the garage. When asked by his father on-air why he didn't respond, the boy replied, "You guys said we did this for the show." When Falcon’s father, Richard Heene, was pressed to explain what his son meant, he became uncomfortable, finally saying he was "appalled" by the questions, adding that Falcon was likely referring to all the media coverage.

Authorities say they don’t believe the case is a hoax, but will question the family further in light of the boy’s comment on CNN.

So what do you think?
