Well let’s see - honeymooned in the communist Soviet Union, he and his wife went back again for a fact finding mission to the communist Soviet Union and came back praising their policies and “palaces of culture”, praise of the communist Castro regime and its policies, praise of the Sandinistas, praise of communist China’s policies, top advisers support Chavez / Maduro’s communist regime, the project veritas videos of his campaign staff, etc. Gee, I wonder what would make the President think such a thing about Sanders?
No one else news worthy has ever publicaly stated such.
For accuracy, he didn’t really honeymoon in the Soviet Union. He said it was “like a honeymoon”. Bad enough.
