Jeff Flake threatens to block Trump's appellate court nominees over Cuba travel, tariffs

According to one source, Flake wants to spur discussions on travel restrictions to Cuba as well as issues related to tariffs.

“We’re discussing it,” the Arizona Republican said in a brief interview with CNN as he came out of an immigration negotiation.

Flake sits on the Judiciary Committee, where Republicans have a slim 11-10 advantage over Democrats. If he does not relent, he could bring the work of the powerful committee to a halt as it applies to appellate court nominees, who are often voted out on party lines.
