The motive for attempting to extort Ukraine into providing dirt on Biden was clearly for Trump to use in the election, that makes it illegal.
You're a liar. There was no attempt to extort and there was no request for "dirt" on Biden. Biden admitted to a crime and asking for an investigation into that crime is not illegal.
The conditions Trumpybear put on the Ukraine leader for the military aid it needs to stave off Russian aggression were pretty clear. Specifically he asked for help with information that can be used in his presumed presidential bid in 2020. Targeting the CT theories about the DNC Servers, Hillary's Server, and Corruption involving Biden's family.
Makes me wonder what other leaders has the Trumpybear leaned on to support his anti-Western Alliance agenda.
