Attorney General Jeff Sessions expressed skepticism that a federal judge who serves in Hawaii had the power to block President Donald Trump’s retooled travel ban, which has been stuck in the courts since last month.

“I really am amazed that a judge sitting on an island in the Pacific can issue an order that stops the president of the United States from what appears to be clearly his statutory and constitutional power,” Sessions told “The Mark Levin Show,” a conservative talk show, earlier this week, according to a report by CNN’s Andrew Kaczynski.

U.S. District Judge Derrick Watson, a Hawaii native, issued an order March 15 that put a stop to important aspects of Trump’s second travel ban. That order, which applies nationwide, is being challenged by Sessions’ Department of Justice before the U.S. 9th Circuit Court of Appeals, based in San Francisco. A Virginia-based court is considering a separate Justice Department appeal to a Maryland ruling against the travel ban

The night Watson issued his ruling, Trump complained to a booing audience in Tennessee that the judge’s ruling was “flawed” and that it “makes us look weak.” Watson has reportedly been the subject of threats for ruling against the president’s executive order, which would limit travel to the U.S. from six Muslim-majority countries and halt refugee resettlement programs.

The two senators from Hawaii, both Democrats, reacted strongly to Sessions’ comment. Sen. Mazie Hirono likened his remarks about Watson to “dog whistle politics.”

Mr. Attorney General: You voted for that judge. And that island is called Oahu. It’s my home. Have some respect.
