The article quotes you provided, still don’t answer the question:
“What crime did Trump commit for which he should be impeached?”
The crimes pointed out, are NOT IMPEACHMENT-WORTHY.
The President and Sarah Sanders cannot do it alone. He's going to need Republicans in both houses to fight for him at the top and in every committee and subcommittee, the same way the RATS find them. Not with the same tactics, but with the same ferocity and committment. He definitely needs his administration to have his back especially at DOJ where someone has to run all out of bubblegum in dealing with the southern district of NY office. And, of course, he needs us.
