John Boehner backed out of a deal to join a marijuana lobbying group — but only after he allegedly stole its data and talking points to form another, pro-weed lobbying outfit of his own, an explosive lawsuit claims.

The former House speaker signed an agreement in March 2018 to become co-chair of the 10 Campaign — a weed legalization group that takes its name from the 10th Amendment of the US Constitution, which establishes states’ rights, according to the suit filed in the Superior Court for the District of Columbia.

Less than a year later, in February 2019, however, Boehner announced he was launching a new group called the National Cannabis Roundtable, revealing he had tapped Kathleen Sebelius, the former health and human services secretary, as a co-chair.

The powerful, Washington-based law firm Squire Patton Boggs, where Boehner is a partner, was also a strategic adviser on the project, according to the suit filed against both Boehner and the firm by 10 Campaign’s founder and executive director, James Pericola. He alleges that Boehner’s group, which went on to become a lucrative business, cut him out of its profits despite it being nothing more than a “repackaged version” of his own.
