But Republican Sen. Lindsey Graham said he already had concerns

In a post on Truth Social on Sunday night, the former president offered his gratitude to law enforcement.

“I would like to thank everyone for your concern and well wishes – It was certainly an interesting day! Most importantly, I want to thank the U.S. Secret Service, Sheriff Ric Bradshaw and his Office of brave and dedicated Patriots, and, all of Law Enforcement, for the incredible job done today at Trump International in keeping me, as the 45th President of the United States, and the Republican Nominee in the upcoming Presidential Election, SAFE. THE JOB DONE WAS ABSOLUTELY OUTSTANDING. I AM VERY PROUD TO BE AN AMERICAN!” he wrote.

President Joe Biden and Vice President Kamala Harris were briefed on the “security incident at the Trump International Golf Course,” the White House said in a statement Sunday afternoon.

“They are relieved to know that he is safe. They will be kept regularly updated by their team,” the White House added.

Biden said in a statement Sunday night: “As I have said many times, there is no place for political violence or for any violence ever in our country, and I have directed my team to continue to ensure that Secret Service has every resource, capability and protective measure necessary to ensure the former President’s continued safety.”

Late Sunday night, Harris said that she was “deeply disturbed by the possible assassination attempt of former President Trump” and also condemned political violence.

“As we gather the facts, I will be clear: I condemn political violence. We all must do our part to ensure that this incident does not lead to more violence,” Harris said.

Harris said that she is “thankful” that Trump is safe. She also commended law enforcement for their work. The vice president also reiterated Biden’s message that the administration would “ensure the Secret Service has every resource, capability, and protective measure necessary to carry out its critical mission.”

After being briefed on the incident, Senate Majority Leader Chuck Schumer said in a statement, “There is no place in this country for political violence of any kind.”

“The perpetrator must be prosecuted to the fullest extent of the law,” Schumer added.

House Speaker Mike Johnson, who was also briefed on the situation, said he and his wife spent time with Trump at Mar-a-Lago Sunday after the incident.

“Kelly and I are departing Mar-a-Lago, where we just spent a few hours with President Trump and are thanking God for protecting him today—once again,” he wrote on X.

Two of Trump’s senior advisers, Susie Wiles and Chris Lacivita, told campaign staffers to stay “remain vigilant” following the apparent attempted assassination attempt.

“We ask that you remain vigilant in your daily comings and goings,” the note sent to staff on Sunday night read. “Be observant and maintain a constant level of situational awareness. We urge you to always follow direction from law enforcement, including USSS, local police, and office armed security guards.”
