'He's just going to rattle off:' Ex-aide slams Trump for cold complaints and golf boasts

A former staffer issued a stern warning to former President Donald Trump over complaints that he's the victim of a political witch hunt in a "cold on purpose" courtroom where he claims he's treated like Nelson Mandala.

Former deputy press secretary Sara Matthews spoke on CNN Monday about Trump's off-the-cuff rants outside the Manhattan criminal courtroom where he stands accused of falsifying business records to cover up hush money paid ahead of the 2016 presidential election.

"He's just going to rattle off whatever's on his brain," Matthews said. "He needs to be more disciplined talking about the issues that voters care about, even when he's doing these little press conferences before and after his courtroom appearances.

"He's talking about things, like complaining about how cold he is, and not really talking about the heart of the issues that Americans care about."

Matthews also discussed recent news that Trump was heard cussing and fuming during a speech to donors at his Mar-a-Lago club, during which he attacked special counsel Jack Smith and complained about President Joe Biden's "Gestapo."

"When these donors are showing up to fundraise or with Donald Trump, there probably not there for a campaign-like speech," Matthews said. "They are more there to be entertained."

Once again, Matthews challenged Trump's message.

"It didn't feel like the most inspiring speech," Matthews said. "He's talking about his golf game and how he wins tournaments that his own club — that he's hosting, mind you.

"He was complaining about different, various things such as the legal troubles that he's facing. He used profanity... when referencing Jack Smith. He was bragging about how much Mar-a Lago is worth — these aren't necessarily the things that I think help move the needle with wanting to bring in donors and more money."

However, Matthews acknowledged that some of what he's doing is working with donors as the campaign boasted a $15 million bump in March, up from around $11 million February.

She noted, "So it does seem that donors are now buying into his candidacy a little bit more."
