National Security Advisor H.R. McMaster might be the next high-profile White House exit as he might get the sack. Just days after the exit of Secretary of State Rex Tillerson, US President Donald Trump has decided to sack McMaster, The Washington Post reported Thursday.

According to the paper, Trump is discussing potential replacements for McMaster, and is waiting to have a replacement in place before making a move. Commenting on the speculation, White House spokeswoman Sarah Sanders said that there were no changes at the National Security Council.

“Just spoke to @POTUS and Gen. H.R. McMaster – contrary to reports they have a good working relationship and there are no changes at the NSC,” Sanders wrote on Twitter.

The Post said that some in the White House were hesitant to remove McMaster until he had “a promotion to four-star rank or other comfortable landing spot.”

This is a departure from the manner in which Tillerson was removed from office. Trump had announced the sack on Twitter and dd not give him a reason for his dismissal. A top aide said Tillerson did not speak to the president before his firing was announced

The Post added that education secretary Betsy DeVos and housing and urban development secretary Ben Carson look most likely to get the axe next.
