U.S. Sen. Tom Carper, D-Del., a senior member of the Homeland Security and Governmental Affairs Committee, said in a Jan. 31 statement he opposes the nomination of Rex Tillerson to the position of secretary of state.

Carper said he questions Tillerson’s ability to “stand up to President Trump and his reckless assaults on our values and his casual dismissal of longstanding U.S. allies.”

“Now, perhaps more than ever, we need a leader at the State Department who will reassure our allies of America’s commitment to democracy and humanitarianism and instill a sense of confidence in the department’s employees. I am not confident that Mr. Tillerson is that person, and I cannot support his nomination to be our next secretary of state.

Though Carper commended Tillerson as “a man of faith who has led a successful business,” he was unimpressed with Tillerson’s hearing. Still, Carper said, he is cautiously hopeful.

“I hope I am wrong and that Mr. Tillerson becomes a strong voice in the Trump Administration to maintain and uphold our values across the globe.”
