We know Russia helped Trump get elected
If this is true, and Trump was involved in the release of this information...it is grounds for impeachment
If he promised or gave Russia anything in return......It is Treason
Hillary should have been indicted and in prison for her illegal bathroom server and mishandling classified info. The "information" you whine about was simply proof that Hillary had classified info on her server and that (the 30,000 missing emails) were hacked by Russia, scattering classified info. Trump was simply trying to prove how slimy Hillary was. She sold US secrets, he wanted to prove it. The problem was that the Russians wanted to keep that hole card in case Hillary won (which was predicted). The GOP Congress will never impeach Trump for showing how the democrats cheated in 2016. The Senate could never convict Trump on the zero evidence presented.
Treason is what Hillary did with classified information, and letting four Americans die in Benghazi.
