"But, again, Trump is the only one right now who can reopen government."
Trump did say what he said. You're right about that. How would you like him to FULLY re-open the government (it is partially shut down now)? Should it be like the opening ceremonies of the Olympics? Should he get hold of the world's biggest megaphone and broadcast it to the sky? Hire a marching band to carry a giant banner through the streets of D.C.? If, like Trump, YOU were the only one who could re-open the government, how would you do it? How would you pay for it, since you have no power of the purse?
The fact that you said "I just said above there is room to blame for both sides" completely contradicts your original point. Actually, you're right about "there is room to blame for both sides", but you chose to only focus on the President.
Then what Congress should do -- if they were so outraged -- is pass a bill that is veto-proof. See, checks and balances.
