Former President Donald Trump has left his Bedminster, New Jersey, golf club to begin his travel day to Florida.

Trump is expected to board his plane at Newark Liberty International Airport to take him to Florida, one day before his court appearance, to meet with potential legal counsel for in-person interviews, sources told ABC News.

The hunt for new counsel comes after Trump's attorneys on this case, Jim Trusty and John Rowley, resigned on Friday, just hours after Trump was informed of the indictment.

Sources told ABC News that it's unlikely Trump will have a full team set in time for Tuesday's court appearance, but he's expected to have attorney Todd Blanche, who is representing Trump in the Manhattan district attorney's probe into hush money payments made to Stormy Daniels, by his side. Attorney Chris Kise, who is based in Florida and working on other matters on behalf of the former president, is likely to also be in attendance, but plans were not solidified as of Sunday evening, sources said.

Donald Trump is expected to head to Florida midday Monday ahead of his first appearance Tuesday before a federal judge regarding the 37 counts he faces from Special Counsel Jack Smith's investigation, sources familiar with the planning told ABC News.

The Trump campaign on Sunday announced that the former president is scheduled to deliver remarks at his Bedminster golf club in New Jersey at 8:15 p.m. ET on Tuesday, after his scheduled court appearance in Florida earlier that afternoon where he will be arraigned on his 37-count indictment.

After Trump was arraigned in his criminal case in New York City in April, and pleaded not guilty, he similarly addressed supporters -- that time from his Mar-a-Lago estate in Florida.

House Speaker Kevin McCarthy went to bat for former President Donald Trump during his first appearance in the Capitol since the 37-count indictment against Trump was handed up in Florida last week.

Asked by reporters whether it was a good look for Trump to have stored boxes of documents in a Mar-a-Lago bathroom, McCarthy responded, "I don’t know. Is it a good picture to have boxes in a garage that opens all the time?" McCarthy said, drawing comparisons to the circumstances surrounding documents found in President Joe Biden's possession.

"A bathroom door locks," McCarthy added.

McCarthy repeatedly slammed the FBI and Department of Justice for failing to indict Biden, falsely equating the crimes Trump allegedly committed with Biden's own handling of classified documents.

"I think President Trump has not been treated equally like everybody else in this process," McCarthy said.

"You raid one house and you don’t raid the other -- that's a little different, and that’s not fair," he said.

McCarthy said he has not spoken to Trump since the indictment was handed up. He said he's read "a lot of portions" of the indictment but not the entire 49-page document that was unsealed Friday.
