Bush White House defends Pakistan's Musharraf

The White House is expressing its support for Pakistani President Gen. Pervez Musharraf even as Vice President Dick Cheney presses Pakistan to crack down on extremists along its lawless border with Afghanistan. US lawmakers and Bush administration officials are eager to see Musharraf's government make stronger efforts against militants said to be using Pakistan as a base for attacks on US forces in Afghanistan. But the White House also wants to defend Musharraf, a crucial US ally who has been targeted by extremists.
