Trump was seen as someone who couldn't properly spell 'Middle East,' according to the former president's advisor and billionaire friend

Some of his clients at his private equity real estate firm mocked the former president's intelligence, according to his former advisor.

Tom Barrack took the stand in his own trial on Monday. The billionaire is accused of lobbying the Trump administration on behalf of the U.A.

During his testimony, Barrack said that his relationship with Trump was bad for his business.

It seems that Barrack's clients didn't pay much attention to Trump's spelling.

According to The Times of Israel, Barrack testified that the former president couldn't spell Middle East. It was a nightmare.

Barrack is accused of obstruction of justice and lying to the FBI, as well as using his connection to Trump to push favorable policies for the Emiratis.

The man pleaded not guilty to the charges. The attorney for Barrack did not reply to the request.

Barrack was friends with Trump in the 1980's. A source told CBS News that they have spoken at least once since Barrack's trial began.
