The Trump administration set the Russia tariff to zero, and we do still import stuff from Russia in spite of all the sanctions and set the blanket ten percent rate on Ukraine as you write. Maybe this is simply the current administration's national security interest.
Most of Tulsi Gabbard's professed foreign policy beliefs prior to being added to this administration echoed Russian state policy, she called it being independent. Tim Pool was just added to White House press pool, he claims he was fooled into repeating information provided by Russia state media, after it was revealed they paid millions to him to do so. There is an awful lot of smoke here.
