In February 2019 , in response to reports of the EPA intending to decide against setting drinking water limits for perfluorooctane sulfonic acid ( PFOS ) and perfluorooctanoic acid ( PFOA ) as part of an upcoming national strategy to manage the aforementioned class of chemicals , Capito was one of twenty senators to sign a letter to Acting EPA Administrator Andrew R. Wheeler calling on the agency " to develop enforceable federal drinking water standards for PFOA and PFOS , as well as institute immediate actions to protect the public from contamination from additional per - and polyfluoroalkyl substances ( PFAS ) . " Capito has sponsored approximately 40 bills about international trade and international finance , the most of any other legislative topic during her career . Capito has criticized the vulnerabilities in current national security policy in the wake of the San Bernardino terrorist attack and has sponsored 8 bills on the military and national security . Capito was one of 47 Republican senators to sign Senator Tom Cotton 's open letter to the Iranian government in 2015 . The letter , which sought to dissuade Iran from reaching an agreement with President Barack Obama regarding nuclear peace , was described by the White House as " undercutting foreign policy "
