But in the days before her visit, Pakistanis reacted with outrage to a bill that would provide them with $1.5 billion in economic aid.
Like many Pakistanis, Riaz Khan said he had no trust in American intentions even when theyre trying providing Pakistan with money designed to create jobs, roads, and increase education.
Khan, a driver in Peshawar, lost nine members of his family who had gone shopping for a wedding in Mina bazaar.
Where there used to be laughing and rooms full of women and children in his house, he says there is emptiness and silence today.
"The Taliban, the Indians, and the Americans. They are playing a game with us," he says.
Siraj ul Munir, whose Mina Bazaar shop was destroyed in the explosion, says the U.S. has helped ruin their futures.
"We are wondering what will become of our future generations who today ask us, 'Father, why do these bomb blasts take place? Who are these bombers?' We can't answer them," he says. "We are innocent people. Tell us what we did to deserve this. It's since the arrival of the Americans that there's been a spike in all this violence."
