The Senate Appropriations Committee's measure demands Kerry's agency implement recommendations of a U.S. investigator for Afghan reconstruction. If the State Department doesn't report progress, he loses a quarter of his salary for three months next year.
The conditions also apply to the U.S. Special envoy to Afghanistan.
For Kerry, whose assets totaled at least USD 184 million according to a 2011 Senate disclosure, it hardly matters. His wife, Teresa Heinz Kerry, is reportedly worth more than USD 1 billion.
Still, some Democrats opposed the amendment to next year's foreign operations bill.
