Three branches of the U.S. military now lack Senate-confirmed chiefs amid a standoff over Pentagon nominees in the upper chamber.

As Adm. Mike Gilday relinquished command of naval operations on Monday, Defense Secretary Lloyd Austin issued a warning about the national security implications of being forced to rely on acting leadership.

“Because of this blanket hold, starting today, for the first time in the history of the Department of Defense, three of our military services are operating without Senate-confirmed leaders,” Lloyd said during a ceremony at the U.S. Naval Academy.

“This is unprecedented, it is unnecessary, and it is unsafe,” he added before calling on the Senate to end the deadlock.

President Joe Biden nominated Adm. Lisa Franchetti to lead the Navy, but she took over command in an acting capacity on Monday, joining leaders stuck in similar positions heading the Marine Corps and the Army.

The bottleneck can be traced back to February, when Sen. Tommy Tuberville (R-AL) placed a “hold” on general and flag officer nominations in protest of a Pentagon policy allowing female service members expense-paid travel and up to three weeks leave for an elective abortion that he claims is illegal.

In upholding his stance, Tuberville has objected to allowing the Democrat-controlled Senate from quickly approving the nominations in batches through a “unanimous consent” agreement.

Despite pushback from the Pentagon and other lawmakers, Tuberville has denied that his hold is hurting military readiness and insisted that the upper chamber can still hold votes through regular order to approve individual nominations if necessary.

“Contrary to false reporting, no jobs are going unfilled while the hold is in place,” Tuberville spokesman Steven Stafford told media outlets in a statement. “Instead, highly experienced acting officials are serving in these roles.”

Democrats have reasoned that it would take too long to get through the backlog with individual votes.

“It would paralyze the Senate if all of us had to take one roll call vote after another just to confirm routine, apolitical, qualified generals and other flag officers,” Senate Majority Leader Chuck Schumer (D-NY) said in remarks earlier this year.

Hundreds of military confirmations have been held up so far, according to the Department of Defense.

One leader who could soon be caught up in the impasse is Gen. Charles “CQ” Brown Jr., Biden’s nominee to become the next chairman of the Joint Chiefs of Staff as Gen. Mark Milley’s term is set to expire in October.

A Fulton County, Georgia, grand jury returned a 98-page indictment on Monday night in the criminal investigation into former President Donald Trump’s alleged efforts to overturn the results of the 2020 presidential election.

The 41-count indictment charges 19 individuals, including Trump, Rudy Giuliani, John Eastman, Mark Meadows, Ken Chesebro, Jeffrey Clark, Jenna Ellis, Ray Stallings Smith III, Robert Cheeley, Mike Roman, David Shafer, Shawn Micah Tresher Still, Stephen Lee, Harrison Floyd, Trevian Kutti, Sidney Powell, Cathleen Latham, Scott Hall, and Misty Hampton.

Fulton County District Attorney Fani Willis pursued charging individuals under Georgia’s RICO Act which allows prosecutors to “string together crimes committed by different people toward one common goal,” Axios reported, which makes it very difficult for defense attorneys to implement a “coherent trial strategy.”

The lengthy prison sentences that come with being convicted of RICO violations are “a major incentive for co-defendants to seek deals in return for new evidence,” the report added.

In the state of Georgia, the governor does not have the ability to pardon convicts, that power rests with a Board of Pardons and Paroles, which “requires that a sentence be completed at least five years prior to applying for a pardon,” the report added. A U.S. president would not be able to pardon Trump in the case.

The case can also be broadcast on television so the public is able to witness all the evidence that is being presented.

The Trump campaign released a statement that called Willis a “rabid partisan who is campaigning and fundraising on a platform of prosecuting President Trump through these bogus indictments.”

The statement claimed that Willis “strategically stalled her investigation to try and maximally interfere with the 2024 presidential race and damage the dominant Trump campaign” and that the accusations contained in it were “fabricated.”

The statement blasted the indictment as “election interference or election manipulation” and said that Trump used his First Amendment rights to challenge what he has claimed was a “rigged and stolen election that the Democrats do all the time.”
