Oh no, there's a difference here. Tip was the House Speaker in the Reagan years, he had actual control of the House, a result of his leadership of the side who won the most seats in an election.

Kushner has never won an election. His only qualifying trait is the fact that he is married to the President's daughter.

I would expect that Jeffries would talk with the White House from time to time. But if Jeffries were a smart politician, he would publicly point out how he had to go to the President's son-in-law to get anything done, and let people realize how bonkers that is. Alas, Jeffries has proven to be not so smart.
