Hillary didn’t hide her policy. She called Putin Hitler, and she called for war against Russia in Syria. Trump refused to prosecute that war ( no fly zone), and stopped our war on Russia’s ally, Assad
In fact Hillary is quite notorious in Russia and was for a long time.
When her husband was into some corrupt anti-Russian stuff even his puppet Yeltsin did not agree to pull for him back to 1990s he sent Hillary directly to Russian governors of the states his donors had interests in to persuade them to do what he wants.
