President Donald Trump and first lady Melania Trump have marked 24 years since the Sept. 11, 2001, attacks at a service at the Pentagon.

While traditionally observed near the building’s memorial outside the Pentagon’s walls, it was moved Thursday to the internal courtyard because of security concerns.

The 9/11 remembrances are being held during a time of increased political tensions after conservative activist Charlie Kirk was shot and killed while speaking at a college in Utah.

The Secret Service has joined the Yankees in warning fans of very long security lines being likely for tonight’s game, due to President Donald Trump being in attendance.

“If you are attending tonight’s @Yankees game, plan on arriving early and consider leaving your bags at home to help speed up the security screening process,” the Secret Service posed on X.

That followed the Yankees saying earlier that ticketholders “are strongly urged to arrive as early as possible.”

Gates are opening more than three hours before first pitch between the Yankees and Tigers in the Bronx at 7:05 p.m. ET.

The press gate at Yankee Stadium opened a half-hour later than the 2 p.m. scheduled time.

A member of Secret Service gave reporters instructions to leave line up bags for inspection, which included a bomb-sniffing dog and going through a metal detector.

An NYPD helicopter flew overhead.

Trump is attending to help mark the anniversary of the Sept. 11 attacks.

His attendance at the U.S. Open last weekend in New York sparked very long security lines.
