Vice President Mike Pence spoke to Fox News on Tuesday night, vowing to push back against the career diplomats testifying in the ongoing impeachment probe.

“We are going to drain the swamp," he said. "But an awful lot of the swamp has been caught up in the State Department bureaucracy and we’re just going to keep fighting it.”

His statement echoed language used earlier by White House press secretary Stephanie Grisham, who called the testimony of former US Ambassador to Ukraine Bill Taylor a “coordinated smear attack from far-left lawmakers and radical unelected bureaucrats.”

Later, when asked by Fox News host Laura Ingraham if he was ever comfortable with the involvement of President Donald Trump's lawyer Rudy Giuliani in regard to Ukraine, Pence didn't directly say yes.

“My involvement in Ukraine was all directly from my conversations with the president, and my conversations and meetings with President Zelensky," Pence said.

He added that “we were supporting and encouraging Ukraine to deal with years of corruption and calling on European allies to do more to support the Ukraine people.”
