Trump names Adam Telle as acting Army secretary after Driscoll resignation.

Sean Parnell, the Pentagon's chief spokesman, is the frontrunner to replace Dan Driscoll as Army secretary. Driscoll resigned earlier this week.

• Parnell has served as Pentagon spokesman since the start of Trump's second term.
• Rep. Brian Mast, who chairs the House Foreign Affairs Committee, is a second candidate.
• Mast recently met with Hegseth; sources said the meeting concerned the Army secretary role.
• House Armed Services Chair Mike Rogers called Mast a potential fit for the job.

Why it matters: The Army secretary vacancy comes as Hegseth's leadership changes have drawn questions about stability in the service. One administration official argued Parnell's familiarity with the Pentagon eliminates any learning curve.

• Parnell faces past domestic abuse allegations that could complicate Senate confirmation with GOP hawks.
• One official said Mast's public support for Israel could fracture a portion of Trump's political base ahead of midterms.

What’s next: Trump has not announced a nominee or a timeline, per White House spokeswoman Anna Kelly.

• Kelly said anonymous claims about the president's thinking should be treated as speculation.
• Will past allegations against Parnell cost him enough Republican Senate votes to block confirmation?
• Would Mast give up a safe House seat and the Foreign Affairs Committee chair for the Army post?
