The house has power to try to do whatever it wants to try. Those who disagree have the right to appeal that in the courts, which is what Trump did. If they didn't have the urge to jam this through, in a 100% partisan sham, they would have waited for the courts to rule. There is no obstruction of congress. That article should be summarily dismissed.
Besides, now, all of a sudden, your side doesn't think the courts should be involved in presidential matters?
Just try to be consistent, for a change.
