Since President Obama took office, the U.S. has made considerable progress in overcoming a problem that has bedeviled presidents since Richard Nixon — dependence on foreign oil.

When U.S. oil dependence peaked at 60 percent in 2005, then-President George W. Bush said the country had a serious problem and was "addicted to oil."

Oil imports were down to 49 percent in 2010, and the Energy Information Agency predicted Tuesday that imports would drop to 36 percent by 2035.

Mitt Romney has filed his tax returns – to the voters. And to no one's surprise, the former Massachusetts governor, private equity firm exec and GOP presidential contender makes a tidy sum.

With New York's legalization of same-sex marriage effectively doubling the number of Americans living in states where gays can marry, gay advocates like to say 2011 was a big year.

It's hard to imagine another doubling this year, but proponents are still hoping to build on last year's success. Same-sex marriage is currently legal in six states plus Washington, D.C., and it may come up for a vote in six more. All the while, legal challenges are pushing the issue closer to getting an opinion from the U.S. Supreme Court.

Google will begin allowing users to add nicknames on Google+, Bradley Horowitz, the vice president of product at Google's social network said Tuesday.

You might have heard about a major solar storm that is hitting Earth right now. It's the biggest to hit us since 2005. You've also probably heard a few pople say, "I didn't feel anything."

As our friends at 13.7 explained earlier today, the storms have the ability to disrupt sensitive electronics and even the power grid. Usually none of those things happen. But, today's solar storm did cause a bit of disruption.

Robert Siegel talks with Sherif Mansour about the events that have unfolded in the year since the Egyptian revolution began. Mansour is an Egyptian democracy activist, who is also a senior program officer for Freedom House's Middle East and North Africa programs.

Mitt Romney released his tax returns for 2010 and 2011, after earlier suggesting he would wait until after winning the GOP nomination. While Romney's total tax bill was in the millions, his tax rate was actually lower than that of many middle-class Americans.

NEAL CONAN, HOST:

It's Tuesday, and time to read from your comments. During last week's show on love and autism, many listeners called and emailed, including Eric from Red Bluff, California. We read his email on the air. I will be a 40-year-old virgin in September. I dated once, when I was 32. Other than that, I've had no love interest where the love was reciprocated. I did not expect to ever find love. I do not believe I could be loved. That is all.
