U.S. relations with Pakistan will suffer if Islamabad does not probe irregularities in last month's election and rerun votes if needed, said Donald Lu, the top U.S. diplomat for South Asia. Lu told a House subcommittee on March 20 that the United States had "serious concerns" about the conduct of the February 8 election and ongoing media disruptions. Should the Election Commission find that these irregularities are substantiated, it should “rerun elections where there's been interference," Lu said. "It will be an impediment to our relationship if Pakistan does not have a democratic process that upholds its own constitution."
