Senate Republicans are growing increasingly exasperated over President Trump's refusal to give them permission to move tough bipartisan sanctions legislation against Russia and countries that buy its oil. Trump pressed European allies over the weekend to levy harsher sanctions against Russia, but he has dragged his feet on the bipartisan sanctions bill, which Republican senators were hoping to get done in July. The failure to act is fueling growing disillusionment among some Senate Republicans that Trump is not serious about helping Ukraine.
