Election 2024 updates: Michelle Obama to speak at DNC this week

During his conversation with Musk, former President Donald Trump addressed the assassination attempt made against him during a campaign rally in July.

"It was amazing that I happened to be turned just at that perfect angle," Trump said of the bullet, which grazed his right ear while his head was turned.

During the discussion, Trump mentioned the man who was killed in the shooting, saying, it was a "very sad situation."

"We lost somebody that was firefighter, a great Trumper," Trump said of Corey Comperatore, adding, "He was a just a fantastic family [man] and a fantastic man."

The conversation between former President Donald Trump and Elon Musk appears to be delayed, with many X users reporting they cannot access the Spaces conversation.

"This Space is not available," appeared for some users on X.

The conversation was scheduled to begin at 8:00 p.m. ET.

A New York judge ruled Monday that the thousands of signatures gathered by Robert F. Kennedy Jr.'s campaign in the state were "invalidated" after a Democrat-aligned group argued he misled voters by listing as his home an address he rarely visits.

The judge, Christina Ryba, ordered the New York Board of Elections to not include Kennedy's name on the ballot this fall.

A lawyer representing Kennedy told reporters last week they would appeal any ruling that went against them.

The ruling could prompt Democrats to bring similar lawsuits against Kennedy in other states where he gathered signatures from registered voters to appear on the ballot.

The FBI is investigating alleged attempts by Iran to target the then-Biden-Harris campaign, sources familiar with the matter confirmed to ABC News.

The alleged targeting via spear-fishing emails occurred before Biden announced he would exit the 2024 presidential race, the sources said.

While the campaign was targeted, the alleged hack was not successful, sources added.

The FBI is investigating a purported hack of the Trump campaign, according to a brief statement from the agency earlier Monday.

The FBI did not attribute the hack to anyone in its statement.

A source familiar with the matter told ABC News that Trump adviser Roger Stone has also been informed that his email accounts have been compromised, and that he's cooperating with any investigation into the matter.

The Washington Post first reported the news.
