The gaslighting here is why Kalim is a waste of time to even try to have a discussion with.
He knows the $3.5MM payment from the former mayor of Moscow's wife is suspicious, he knows Hunter making millions sitting on the board of Burisma (with literally zero experience in energy) is highly problematic, he knows Biden admitted to bribing Ukraine with federal money to fire the prosecutor investigating his son is worse than the impeachment call, he knows private art sales in a gallery owned by a guy with ties to the Chinese gov't for prices that rival Picasso and Van Gogh is problematic, he knows the emails where Hunter complains he's had to give "half his salary his entire life" to his dad are real...so instead he puts all the focus on drugs, dental problems and illegitimate kids with strippers - with some whataboutism lies about Trump's kids.
It's textbook gaslighting and it's about as transparent as it can be. No one gets anywhere, and that's his goal.
