US President Donald Trump’s team began to strengthen security measures following the assassination of conservative activist Charlie Kerk, the Wall Street Journal said on Thursday.

According to a senior official, the Pentagon’s ceremony on the anniversary of the September 11 terrorist attacks was moved to a safer point so that Trump would speak. In addition, measures will apply on Thursday night, when the president will watch the Yankees match in New York. “Those who are on the site around the stadium should expect an increased presence of police,” the secret service said.

In addition to the events of the week, Trump’s team is discussing more broadly about boosting his safety, according to the same official.

The president and his associates have been shocked by the murder. Kerk, who was killed Wednesday by an armed outdoor event in Utah, maintained close relations with Trump, his family, Vice President Jay Di Vance and many new government associates. “The atmosphere is mournful, some are also afraid of their own safety,” a White House official said.

For Trump, the attack awakened painful memories of the attempted assassination against him in July 2024, his associates said. Memories of that day are visible throughout the White House, including a painting in Trump’s large foyer surrounded by agents of the secret service with blood running on his cheek.
