In the wake of Yankee slugger Alex Rodriguez' confession that he used steroids between 2001 and 2003, President Barack Obama called the revelation "depressing news on top of what's been a flurry of depressing items when it comes to major league baseball."

"I think it tarnishes an entire era, to some degree," Mr. Obama said during his first prime-time news conference. "And it's unfortunate, because I think there were a lot of ballplayers who played it straight."

Mr. Obama also recognized the upside of the affair, saying, "What I'm pleased about is major league baseball seems to finally be taking this seriously, to recognize how big a problem this is for the sport, and that our kids hopefully are watching and saying, 'You know what? There are no short cuts, that when you try to take short cuts, you may end up tarnishing your entire career, and that your integrity's not worth it.' That's the message I hope is communicated."

A-Rod revealed to ESPN today that he used banned performance-enhancing substances to justify his 10-year, $252 million contract with the Texas Rangers.
