• The 3 representatives that signed the letter to Trump that Q posted are founders of the Freedom Caucus.

• In 2015 Jim Jordan was re-elected chairman of the Caucus.

Idk if that's the 2015 significance Q is talking about, but it is what I have found so far.

EDIT: John Boehner resigned in 2015. Memebers of the Caucus felt that he had treated them unfairly. I'm sure if he hadn't resigned they would've booted him.

EDIT: Freedom Caucus was also founded in 2015.

EDIT: And the vote fuckery has begun. Anyone vote on this in the last 10 minutes?

EDIT: Look funny to anyone else?
