UPDATE- To those who are quoting the "debate clause"... The debate clause cannot be used as a shield to protect people from accountability for making false Criminal allegations against someone. That is NOT what our founders intended and certainly not a standard any rational thinking person ought to advocate.
In case you are interested-
Every House Member who testified that Donald Trump "incited" a riot is guilty of violating 18 USC 1001(a)(2).
They knew or should have known it is a legal impossibility for Trump to have incited a riot. Therefore their accusation on Congressional record at an official Congressional proceeding violates federal statute subjecting them to penalties up to 5 years in prison.
All their rhetoric about "Constitution" & "rule of law" and all the while they were actively violating federal law.
To answer your questions-
1. They will continue to do it all as long as we allow them to get away with it
2. We make them accountable by getting control of our State and local governments so we can strip them of power and funding.
