White House summons Rod Rosenstein
"According to NBC News Pentagon correspondent Hans Nichols, Rosenstein was “was seen leaving the White House at 11:28 a.m.” on Tuesday."
I think this has to do with the Russian Maria Butina being arrested yesterday with her involvement in funnelung money to the NRA. She paid for Trumps super PAC rep David A. Clarke Jr. to visit her in Russia. She also met with Trump Jr.
Connect the dots, Trumps election super PAC getting money funneled from the same Russian who funneled millions to the NRA. More direct verifiable evidence of Russian collusion.
