The recorded evidence of the Ukrainian bribery is claimed by the Ukrainian oligarch to be in his possession. Congress has no subpoena power over Ukrainian oligarchs and he has no motivation for self incrimination. The proof is in the pudding, biden’s admission, the actions taken, and the bank deposits. There’s no value in relying on Ukrainian proceedings; you get what you pay for.
More importantly, anyone who doesn’t see evidence for impeachment and removal (Romney) only needs to visit the southern border. Adding to the NY mayor and governor’s pleadings, now the dim governor of AZ is demanding over $50billion to deal with the illegals. Dereliction of duty and a threat to National security is enough.
