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.

Some of Trump's 2024 rivals have started to weigh in following news of a federal indictment against the former president.

Florida Gov. Ron DeSantis denounced on social media the "weaponization of federal law enforcement" and said that a "DeSantis administration will bring accountability to the DOJ, excise political bias and end weaponization once and for all."

Former Arkansas Gov. Asa Hutchinson said in a statement to ABC News that the criminal proceedings are a "major distraction" and "reaffirms the need for Donald Trump to respect the office and end his campaign."

"With the news that Donald Trump has been indicted for the second time, our country finds itself in a position that weakens our democracy," Hutchinson said. "Donald Trump's actions -- from his willful disregard for the Constitution to his disrespect for the rule of law -- should not define our nation or the Republican Party. This is a sad day for our country."

Former New Jersey Gov. Chris Christie told PBS that if Trump "committed a crime and there is evidence beyond a reasonable doubt to prove that crime, then he must be charged," and that not doing so would set the rule of law in the U.S. back.

Christie later tweeted, "We don't get our news from Trump's Truth Social account. Let's see what the facts are when any possible indictment is released. As I have said before, no one is above the law, no matter how much they wish they were. We will have more to say when the facts are revealed."
