Trump slams Robert Mueller and Jeff Sessions in new tweet storm

Trump again slams special counsel Robert Mueller's Russia probe and his own attorney general, Jeff Sessions, for allowing the "witch hunt" to take root in the first place. Trump says fired FBI agent Peter Strzok should be "criminally investigated." Trump escalates his attacks against former aide Omarosa Manigault Newman, calling her a "dog" and a "crazed, crying lowlife."
