WATCH: Karoline Leavitt returns for White House briefing as Trump readies primetime speech

White House press secretary Karoline Leavitt is back at the briefing room podium on Thursday, the first time since she went on maternity leave earlier this year.

White House press secretary Karoline Leavitt is expected to hold a news briefing at 1 p.m. EDT. Watch in the video player above.

Leavitt last held a briefing on April 24 before taking leave and giving birth to a daughter on May 1. She returned to work at the White House in late June.

While she was away, the White House leaned on a rotating cast of cabinet members to fill in, including Vice President JD Vance, Secretary of State Marco Rubio and Treasury Secretary Scott Bessent.

Leavitt's return comes ahead of a national address Trump is scheduled to deliver Thursday evening. The president has said he will discuss topics including elections and voting machines.

She kicked off the briefing with a scheduling update, highlighting Trump's national address planned for Thursday evening.

"President Trump will deliver a major address to the nation on protecting the integrity of our elections. And we encourage every American to tune in," Leavitt said.

She added that Trump will head to New York City on Friday for a FIFA reception at Trump Tower ahead of his appearance at the World Cup final between Spain and Argentina on Sunday.

Asked if Trump will be cheering for Argentina given the hard feelings he has toward Spain, Karoline Leavitt answered a reporter's question with, "It's a really good question."

"And I'm disappointed in myself for not asking the president before I came out here, knowing you would probably ask," she said at her briefing Thursday. "I haven't talked to him about it. But we'll get you an answer on that. You're welcome to ask him yourself at some point before the game. I'm sure you'll see him, and I'm sure he'll have a fun answer for you on it."

Leavitt says White House staffer accused of profiting off position is on unpaid leave

Asked about reports that a teleprompter operator for Trump is accused of placing online bets using inside knowledge from his job, Leavitt said the employee has been put on unpaid leave.

"I'm aware of the report; the president is too. I spoke with him about it. He believes it's deeply unfortunate and, frankly, a disgrace," Leavitt said Thursday.

Leavitt said she does not know of other White House employees accused of similar allegations, adding that the White House has "extremely strict, ethical guidelines with respect to issues like this."

Reports from ABC News and other outlets say Gabriel Perez, a technical assistant to the president, is in talks with federal regulators to settle allegations that he used inside knowledge from Trump's speeches to win more than $100,000 on the predictions market Kalshi.
