Once the whistleblower exposed this, they went ahead and released the aid. What is the big deal about using an illegal quid pro quo in colluding with a foreign power to interfere in an election??
Baloney. They released the air because the House had just passed a government funding bill that had a line item for even more aid in the next funding cycle, and the Senate leadership told Trump that the aid had to be released unless he wanted to veto the entire spending bill.
What law forbids quid pro quo? How would such a demand be colluding with a foreign power? What law prohibits collusion?
