Of course Schiff can't rule out going for impeachment since he does not know what is in the report. People are making judgments that mean nothing - both sides with no knowledge of what it says, are speculating what is in it. These judgments with no knowledge have been going on for two years.
And, we have "Q" "drops" that say thousands of people, including rich people and most members of congress, the Democrats of course, are going to be arrested and taken to GITMO for military trials and be killed. The Q people think this report now out, had to happen before all the arrests could be made.
My opinion is, until we know what is in it, we don't know what is in it.
