The Washington Post reports:
Special counsel Robert S. Mueller III has alerted the White House that his team will probably seek to interview six top current and former advisers to President Trump who were witnesses to several episodes relevant to the investigation of Russia’s meddling in the 2016 election, according to people familiar with the request.
Mueller’s interest in the aides, including trusted adviser Hope Hicks, former press secretary Sean Spicer and former chief of staff Reince Priebus, reflects how the probe that has dogged Trump’s presidency is starting to penetrate a closer circle of aides around the president.
In addition to Priebus, Spicer and Hicks, Mueller has notified the White House he will probably seek to question White House counsel Don McGahn and one of his deputies, James Burnham. Mueller’s office has also told the White House that investigators may want to interview Josh Raffel, a White House spokesman who works closely with Trump son-in-law Jared Kushner.
