A day after delivering his State of the Union address to Congress, President Obama took his message on the road. Obama hoped that stops at manufacturing sites in Iowa and Arizona would drive home his point that the government should do more to encourage factory jobs.

Treasury Secretary Timothy Geithner told Bloomberg Television today that he's "pretty confident" he won't be asked to stay in his job if President Obama is re-elected for a second term.

The Louvre had a record 9 million visitors last year, and about 10 percent of them were American. Yet the iconic Paris art museum only has four American paintings in its huge permanent collection.

But the Louvre's curators want to change that and heighten the public's knowledge and awareness of early American art with a new exhibit.

Nationwide, French museums own some 2,000 American paintings, but those Whistlers, Homers and Cassatts are exhibited in more modern museums such as the Musee d'Orsay.

"After more than 30 years of handing prayer cards to customers aboard its planes, Alaska Airlines has decided the practice is outdated and will stop doing it on Feb. 1," The Seattle Times reports.

A few things struck us about this news.

Samantha Garvey, the homeless teen who came into the national spotlight after she became a semifinalist in the prestigious Intel Science Talent Search competition, has had a bittersweet 24 hours.
