New York: The governor of the US state of Vermont has become the first Republican leader to support an impeachment inquiry against President Donald Trump after a whistleblower complaint released on Thursday triggered a deepening scandal over the Trump administration's relationship with Ukraine .

Governor Phil Scott said at a news conference on Friday that he wasn't surprised by the news that Trump repeatedly urged Ukraine's President to "look into" Democratic presidential candidate Joe Biden because he's "watched him over the years."

But he cautioned that he wanted to know more before any further actions are taken.

"I think the inquiry is important, yes, and where it leads from here is going to be driven by the facts that are established," Scott said.
