Republican Sen. Rand Paul (KY) is blocking Mike Waltz from becoming President Donald Trump's new ambassador to the United Nations.

Paul addressed the Waltz hold, saying, "They pulled it for now, we're going to see what happens over the next week," Axios reported Wednesday.

Waltz was up for a confirmation vote ahead of the August Recess, when the members flee Washington's heat for their home states, family vacations, or an international congressional delegation trip.

Republicans remain hopeful they can convince Paul to support Waltz or that they can make a deal with a Democrat on the committee, Axios reported.

"If you want to report my opinion," Paul said. "I had an exchange in the committee last week — that's probably the best thing to report."
Paul raked Waltz across the coals during the hearing. Among his issues is Waltz's 2020 vote as a member of Congress to hinder Trump's ability to withdraw troops from Afghanistan.

“I guess it just worries me that you come more from the [former Rep. Liz Cheney] wing of the party than the Donald Trump party,” Paul said.

Before the Senate, Waltz also answered questions about his role in Signalgate last week. The scandal involved Secretary of Defense Pete Hegseth sharing classified information via a Signal chat that included a reporter.

After the incident, Trump announced that Secretary of State Marco Rubio would take over the NSA's job, and Waltz would be appointed to another post. Waltz testified that he had continued to be paid for his job and was never fired.

Waltz also testified that no classified information was shared in the chat. However, a new report Wednesday revealed that a classified message that Hegseth copied into the Signal chat was rated "SECRET."
