On Capitol Hill, President Trump’s pick to serve as U.S. ambassador to the United Nations on Tuesday applauded Republican efforts to defund the U.N., saying he’d go even further if confirmed by the Senate. Mike Waltz testified that, if confirmed, he would work to dismantle the U.N. agency for Palestinian refugees. He also backed Republican efforts to cancel about $1 billion in federal funding to the U.N. as part of the Senate’s rescission package. Waltz served as U.S. national security adviser from January to May before his removal over the “Signalgate” scandal, in which Waltz added the editor of The Atlantic magazine to a group chat about U.S. war plans against Yemen. He was grilled over the scandal by Delaware Democratic Senator Chris Coons.

Sen. Chris Coons: “I mean, this was demonstrably sensitive information. And the question I asked was: Were you investigated for this expansion of the Signal group to include a journalist?”

Mike Waltz: “The White House conducted an investigation, and my understanding is the Department of Defense is still conducting an investigation.”

Sen. Chris Coons: “Was any disciplinary action taken?”

Mike Waltz: “From the White House investigation, Senator?”

Sen. Chris Coons: “Yes.”

Mike Waltz: “No, the use of Signal was not only — not only authorized, it’s still authorized and highly recommended.”
