Sen. Tom Cotton on Wednesday chided Senate Minority Leader Charles E. Schumer for a delay on a confirmation vote for CIA Director Mike Pompeo and suggested Mr. Schumer’s tenure as the top-ranking Democrat in the Senate might improve with “a little more seasoning and experience.” “On this particular instance, though, we all thought he had made a commitment to us that we would vote on Mike Pompeo’s nomination on Friday,” Mr. Cotton told radio host Hugh Hewitt.
