What do we know, that the GOP all agree on: 

The United States Intelligence Community has concluded that the Russian government interfered in the 2016 United States elections. Their report stated, "We assess Russian President Vladimir Putin ordered an influence campaign in 2016 aimed at the U.S. presidential election. Russia’s goals were to undermine public faith in the U.S. democratic process, denigrate Secretary Hillary Clinton, and harm her electability and potential presidency. We further assess Putin and the Russian Government developed a clear preference for President-elect Trump. We have high confidence in these judgments." T

rump himself has agreed to this set of facts.   Is it unreasonable of the Intelligence Community to determine if Trump or his team was participating in this effort? I don't think so.
