A conservative Tea Party group accused former House Speaker John Boehner of being a bitter retiree without much class, after he called Ted Cruz "Lucifer" and a " miserable son of a bitch."

"Boehner's attacks on conservative leaders in Congress isn't going to change the fact that he sold out conservatives, time and time again," FreedomWorks CEO Adam Brandon said. "We hope Boehner finds some class as he continues his retirement. Maybe more time will help him become less bitter."

Freedom Works has long supported Cruz, beginning with his long-shot campaign to defeat the GOP establishment candidate in the Texas GOP Senate primary in 2012.

The group also has a long history of clashing with Boehner, who they believe cut too many deals with Democrats on spending, without fighting for conservative priorities.
