Ex-Clinton nemesis Ken Starr says 'You have to look at everything' in potential case against Trump

He called the dispute between Trump and Comey a case of "he said, he said."

For now, Starr said this morning, the situation is "not anywhere near a crime."

The debate about a potential obstruction of justice case has been largely divided along party lines.

Republican Senate Judiciary Committee Member Mike Lee of Utah told ABC News this weekend that even if former Comey's testimony to Congress was true, there's no evidence of even potential obstruction of justice by President Trump.

"I don't see any evidence of intent to obstruct," Lee said. "I don't see any indication that there was even the potential for corruption here or for obstruction of justice.”

Starr this morning also gave a ringing endorsement of former FBI Director Robert Mueller, who has been assigned by Deputy Attorney General Rod Rosenstein to "oversee the previously confirmed FBI investigation of Russian government efforts to influence the 2016 presidential election, and related matters," according to a statement issued by the Department of Justice in May.

"Bob Mueller has the integrity to call them as he sees them," Starr told “GMA” today.

Starr investigated Bill Clinton’s “Whitewater” business dealings in the 1990s, as well as his extramarital affair with Monica Lewinsky.

He later became president of Baylor University, where he resigned last year from the chancellor role to which he had been demoted amid criticisms of the way the school handled accusations of sexual assault by football players.
