Republicans approve spending plan that will pay for hardline immigration policies; sackings on hold amid concerns they could hit military readiness

• Mass firings could cause ‘monumental’ bill, say experts

National security adviser Mike Waltz told a crowd of Donald Trump loyalists that he believes the president will receive the Nobel peace prize.

“This is the presidency of peace. He’s going to end the war in Europe. He is going to end the wars in the Middle East. He is going to reinvest the United States and our leadership in our own hemisphere, from the Arctic to the border to Panama all the way down to our good friends in Argentina,” Waltz told the Conservative Political Action Conference.

The pause comes after CNN reported on Wednesday that the mass terminations, which could affect over 50,000 civilian employees across the Pentagon, could run afoul of Title 10 section 129a of the US code. Following that report, Pentagon lawyers began reviewing the legality of the planned terminations more closely, the officials said.

That law says that the secretary of defense “may not reduce the civilian workforce programmed full-time equivalent levels unless the Secretary conducts an appropriate analysis” of how those firings could impact the US military’s lethality and readiness. The law also says that mitigating risk to US military readiness takes precedence over cost.
