Martha MacCallum sat down with Vice President Mike Pence for a wide-ranging interview that will air tonight on "The First 100 Days" at 7:00 p.m. ET on Fox News Channel.

Pence addressed the major news stories of the day, including the removal of Steven Bannon, President Trump’s controversial chief strategist, from the National Security Council.

He said Bannon is a "highly valued member" of the administration and this is not a demotion.

"I think with H.R. McMaster’s addition as our National Security Advisor – a man of extraordinary background in the military – this is just a natural evolution to ensure the National Security Council is organized in a way that best serves the president in resolving and making those difficult decisions," Pence said.

He also reacted to the horrific chemical weapons attack in Syria, which he said appears to be the work of Syrian President Bashar al-Assad's regime.

"No American can look at those images and not be heartsick," Pence said. "It is a reflection of the failure of the past administration to both confront the mindless violence of the Assad regime and also hold Russia and Syria to account for the promises that they made to destroy chemical weapons."

As for Trump's upcoming meeting with Chinese President Xi Jinping, Pence said he's expecting a "productive discussion" about the U.S.-China economic relationship.

He added that he expects North Korea and its burgeoning hopes of developing nuclear weapons will also be discussed.

"As the president said this weekend, if China won’t deal with North Korea, we will," Pence said.
