Minnesota congresswoman Michele Bachmann and Texas Gov. Rick Perry are clashing over whether the United States should continue to provide more than $1 billion in aid to Pakistan.
Perry says that Pakistan has shown "time after time" that it cannot be trusted and that he would not send the country "one penny _ period."
Bachmann says Perry's approach is "naive," arguing that the U.S. needs to have a presence in the region to protect its national security. She called Pakistan a "violent, unstable nation" with more than a dozen nuclear sites that could be penetrated.
The Obama administration has said the U.S. relationship with Islamabad is vital to the nation's national security and has urged Pakistan to crack down on the Taliban-linked Haqqani network.
