There has been more upheaval at the National Security Council according to new reports.

"Andrew Peek, the senior director for European and Russian affairs at the National Security Council, has been placed on administrative leave pending a security-related investigation," Axios reported Saturday, citing people familiar with the situation.

"Peek had been expected to attend the World Economic Forum in Davos, Switzerland next week, where President Trump is expected to meet with a number of world leaders as the impeachment trial takes place back in the Senate," Axios added.

Bloomberg News senior White House reporter Jennifer Jacobs offered additional reporting.
