Republicans controlled the House, the Senate & the Executive branch.
During that time a Republican attorney General, and Republican Assistant attorney general, Assigned a Republican ex director of the FBI to investigate Republican Donald Trump in a Republican run & supervised special investigation.
And.... the Republicans try to blame Democrats & the media for their failure to find enough evidence for Trump colluding with the Russian government.
So Republicans are either incompetent investigators or they're covering up for Trump which is it?
