I hold to account whoever has power now. I don't play the "whataboutism" game, because it is unwinnable. There was always someone in the past that has done worse. What matters is progress.
No, you are not. You are blaming Trump for a policy that was started when Obama was President. This isn't a "whataboutism" situation. When called on it, you tried to blame Republican Senators, even though they were in the minority when this policy was started.
Even the fact underlying your basic premise is wrong: Republicans had the majority in both houses of congress in January 3, 2015[3], gaining the Senate after having held the House since January 3, 2011. They continued to hold both in majority until the past midterm elections seated a Democratic house majority this January.
