runner-up Katharine McPhee, recovered from the bronchitis and laryngitis that have kept her off the "American Idols Live" tour, will join her fellow Idol
finalists on a White House visit
McPhee, 22, as well as Idol
winner Taylor Hicks and the rest of the recent season's top 10 contestants, will tour the White House and meet President Bush in the Oval Office before performing that evening at Washington, D.C.'s Verizon Center.
On Thursday, McPhee was to join the "Idols Live" tour in Pittsburgh – her first performance since the tour kicked off on July 6. Earlier that day, she co-hosted The View,
and told viewers, "I didn't really disappear. I was just following doctor's orders. He told me, 'You're not allowed to talk for three weeks.' "
McPhee, who told PEOPLE in June that she'd suffered from an eating disorder
, also said, "People thought the bulimia was the reason I was set back, but it's just not true. I just got sick and I was overworked."
She also denied rumors that she'd stayed away from the tour because she wanted to distance herself from Idol,
saying she's "grateful" for what the FOX talent show did for her.
To close the View
episode, she sang her rendition of "Somewhere Over the Rainbow."
After wrapping the "Idols" tour on Sept. 24, McPhee will record an album
for 19 Recordings Unlimited, serve as spokesmodel for hair-care line Sexy Hair Concepts and co-produce "Red Herring," a play set to premiere at the 10th Annual New York International Fringe Festival on Aug. 12.
