"Putin / U1 will come out post summit (they will try to apply artificial MSM heat to cancel)"
I think what Q means by this is that Putin will reveal either publicly or to Trump(with solid proof) that Rosatom or other russians associated with Uranium 1 gave big donations to Clinton Foundation and in exchange Clinton handed out 20% of U1 ownership to russians.
It's definitely connected to this ongoing lawsuit againts Clinton Foundation, Hillary Clinton herself and many more globalist criminals. Just one of the many crimes she has committed.
