"Let me make it clear that what I've seen yet is a very troublesome telephone call," Hutchinson said in an ABC News interview released Tuesday. "But I have not seen anything yet that would lead me to believe you should remove a president from office."

Asked whether a censure would be a better alternative, the governor said he doesn't think a censure is a "serious part of the discussion."

"The constitution gives the House of Representatives one choice, and that is — impeachment — is their only remedy versus some other process," Hutchinson said.

Trump during the July 25 call with Zelensky, which is at the center of the House's impeachment inquiry, told the foreign leader that he should investigate Democratic presidential candidate and his son, according to a rough transcript released by the White House.

Trump has maintained that he did not do anything wrong.

Hutchinson said he does not think going after the impeachment inquiry process will be enough to defend the president.

"You also have to get in there and address the substantive questions that the American people will be thinking about," he told ABC.

He also said that, as some Republicans have called for, that the public should hear from the whistleblower whose complaint sparked the inquiry.

"Anybody who tries to take down the president of the United states should know ... that's not going to be a private matter," Hutchinson said. "I think that if they move forward with an impeachment process, the American people will want to say we ought to hear from the whistleblower. We ought to be able to weigh the credibility of these witnesses ourselves."
