The telephone call was not about normalizing relations with Russia

Lot's of people seem to be assuming that the promise Trump made to a foreign leader that prompted the whistle-blowing complaint was a promise to Putin to normalize relations with Russia. But Trump has been openly talking about that throughout his presidency. For Inspector General Michael Atkinson, a Trump appointee, to have considered the complaint to be "credible and troubling enough to be considered a matter of 'urgent concern'" which required a report to Congress, it must have been something much worse than merely an improved relationship with Russia.

To be honest, I have no idea what it might be. But for this to happen it had to be something really really bad.
