Clinton in Pakistan to push for greater counterterrorism effort

Adm. Mike Mullen, chairman of the Joint Chiefs of Staff, is accompanying Clinton for what one senior State Department official said would be a "sober" set of talks about the need for Pakistan to root out terrorists in its country.

Clinton asked Mullen to come with her so they could have one meeting where they are delivering the same message at the same time and gauging Pakistani's reaction together, a senior administration official said.
