Former U.S. President George H. W. Bush is continuing to recover at a Houston hospital six weeks after being admitted for a bronchial infection, and it is not clear when he would go home, his spokesman said.

"In recent days he has taken great pride watching big football wins by Texas A&M and the Houston Texans," said the spokesman, Jim McGrath, in a statement. "While no immediate timeline has been set for the President's discharge, the Bushes wish to thank everyone for their many kind messages."

Bush, 88, a Republican who during his one term in office led a coalition that ejected Iraqi forces from Kuwait in 1991, was admitted to Methodist Hospital Nov. 23 for bronchitis. He was transferred to intensive care in December after setbacks including a persistent fever, McGrath has said. Later in December, his condition improved enough for him to be moved to a regular patient room, McGrath said at the time.

Bush has lower-body parkinsonism, which causes a loss of balance, and has used wheelchairs for more than a year.

The 41st U.S. president, and father of former President George W. Bush, served as a congressman, as ambassador to the United Nations, as envoy to China, as CIA director and as vice president for two terms under Ronald Reagan.
