The White House has indicated that this is part of President Trump's promise to drain the swamp.
President Donald Trump is cleaning house at the National Security Council, scrubbing dozens of Obama Administration holdovers in the agency after dumping Lt. Col. Alexander Vindman, the NSC’s expert on Ukraine, who testified against the president in the House Democrats’ impeachment inquiry, late last year.
The White House responded that Vindman serves at the discretion of the president, and Trump is well within his rights to let Vindman go. President Trump himself took to Twitter to defend the dismissal, noting that Vindman ‘was given a horrendous report by his superior, the man he reported to, who publicly stated that Vindman had problems with judgement, adhering to the chain of command and leaking information.”
Vindman’s twin brother, Lt. Col. Yevgeny Vindman, who worked as an attorney for the National Security Council, was also fired on Friday. House Democrats announced Monday that they will be initiating an investigation into whether the two Vindmans were punished for being “whistleblowers” in volation of Federal law.
The Washington Examiner reports, though, that the “house-cleaning” goes deeper than the two Vindmans, and is part of an extensive effort to pare down the NSC and several other agencies, packed with Obama-era officials. Acting national security advisor Robert O’Brien has already cut dozens of personnel and is expected to cut dozens more, letting at least 70 individuals go from the foreign policy and intelligence agency.
