Darling had told Transport Topics on Jan. 11 that he wasn’t concerned about his ongoing acting status.
“I’m going to come to work every day,” Darling said. “I’m going to do my job. The work that we do is important because safe trucking moves the economy. When Congress wants to see me, I will be there.”
Prior to being nominated by President Obama to replace Anne Ferro, Darling had served as FMCSA’s chief counsel since September 2012. Darling came to FMCSA from the Massachusetts Bay Transportation Authority, where he served as deputy chief of staff and assistant general counsel.
