Republicans thwarted a push by Senate Democrats to confirm President Obama's long-stalled sanctions czar on Wednesday.

"Secretary Lew has all but announced that the United States government will allow Iran to dollarize their foreign transactions," he said. "Until President Obama and Secretary Kerry and Secretary Lew publicly and conclusively renounce any intent to allow Iran to dollarize a foreign transaction, I will object to this nomination." 

His comments come after the Associated Press reported last month that the Obama administration was considering allowing some offshore banks to use dollars to do currency trades for financial transactions with Iranian businesses. 

Officials told the AP, at the time, that no decision was finalized and any loosening of the current prohibition would come with several restrictions.

Wednesday marks the one-year anniversary since the Senate received Szubin's nomination, kicking off the confirmation process. 

He was approved by the Senate Banking, Housing and Urban Affairs Committee last month, and is currently filling the post in an acting capacity. 

Democrats, however, argue that he still needs to be confirmed.

Cotton acknowledged that Szubin is "well respected" by both parties. However, he said if Democrats were unhappy about his decision to block the nomination, "they should have considered that before they voted for a deal that gave over a hundred billion dollars to the world's worst state sponsor of terrorism."
