The White House is rapidly ratcheting up its public threats against special counsel Robert Mueller and his team, raising concerns among Democrats and Republicans alike across Washington.President Donald Trump continues to deride Mueller’s investigation into Russia’s interference in the 2016 election as a “witch hunt,” and warned the longtime prosecutor in a Wednesday interview with the New York Times to stay away from investigating his family’s finances, saying it would be a “violation.”The president also pushed the notion that some members of Mueller’s team, who have previously donated to Democratic campaigns, are ethically compromised.
