Trump's own biographer flags latest 'sign of panic' for former president

A biographer of Donald Trump's is seeing the ex-president start to panic after another huge night for the Democratic Party at their convention in Chicago.

David Cay Johnston spotted one of Donald Trump's latest fundraising emails as a sign of anxiety.

The Trump campaign's fundraising numbers have lagged despite hosting the Republican National Convention and naming his vice presidential running mate. In July, he was only able to pull in $139 million compared to Kamala Harris' nearly $500 million.

The language, he pointed out, is "red-baiting," Johnston said, "and sliming of her donors."

The email flashes "EMERGENCY ALERT" at the top and another "ALERT" in a graphic at the bottom. The text is in all caps and begging for help.

"She's expecting millions more dirty liberal dollars to pour in today," Trump's team wrote, revealing the Democrats' high fundraising numbers. "Today might be her best fundraising day ever!"

Indeed, according to the Trump biographer, this is the "latest sign of [Trump's] panic."
