Not that long ago he put 50% tariffs on India for buying Russian oil.
Three weeks ago he signed the Lindsay Graham Sanctioning Russia and Iran Act that allowed him to put 100% tariffs on any country that violates either the Russian or Iranian sanctions. Then HE HIMSELF VIOLATED THE ACT.
Catherine Rampell says best case scenario it would be about 3 weeks of diesel, and based on everything we know she doesn't think Russia can actually fulfill it.
She also said that Congress is already regretting passing the bill because not only did Trump violate it, they have reason to think when the latest tariffs expire Trump intends to use this new law to put new tariffs, he'll just say Canada violated sanctions, China violated sanctions etc, with no proof they did, and then he can levy tariffs
