House Democrats are ramping up their impeachment inquiry into President Donald Trump, and Trump has vowed to fight them. On Wednesday, two individuals associated with Trump’s personal lawyer, Rudy Guiliani, were arrested due to allegations that they funneled foreign money into American elections, and influenced politics on behalf of a Ukranian politician.

Some observers have said the arrests could be a powerful blow to the president when it comes to the inquiry, but former Suffolk County Sheriff and Secretary of Public Safety Andrea Cabral said that House Speaker Nancy Pelosi’s recent decision to open an inquiry amounts to too little, too late.

“I’ll go to my grave believing that the delay in starting it was wrong,” Cabral said during an interview with Boston Public Radio on Thursday. “They could have had articles [of] impeachment for a number of things a long time ago, and been educating the public.”

Cabral said that although the public has begun to change their opinion on impeaching the president, she believes his presidency has been marked by a dangerous, and dramatic turn in U.S. policy that is becoming unsustainable.

“He’s going to continue to do things like this heinous betrayal of the Kurdish people, and be actually ultimately responsible for their deaths based on a phone call he has with a guy who oversees his properties in Turkey,” Cabral said. “He will continue to do things like this because it is in his nature to be destructive.”
