Former US president Bill Clinton and first lady Hillary Rodham Clinton Bush received a standing ovation Monday at the White House when they unveiled their official portraits.

President George W. Bush praised his predecessor's "energy and joy" during a lighthearted ceremony in the East Room of the executive mansion.

"Over eight years, it was clear that Bill Clinton loved the job of the presidency. He filled this house with energy and joy," Bush said.

Bush also noted that Mrs. Clinton is the only sitting senator whose portrait hangs in the White House.

The portraits were painted by self-taught artist Simmie Knox, who has created official portraits of former U.S. Supreme Court Justice Thurgood Marshall and several members of Congress.
