AG Brad Schimel defense of joining Exxon lawsuit "one of the loonier things I’ve heard,” says fellow attorney.

Just a quick reason why AG Brad Schimel is all politics and partisan arm of Scott Walker's political agenda:

JS: The cases, and others, have raised questions by critics who say such legal forays by the Department of Justice have little or no connection to Wisconsin and are chiefly designed to further Republican causes.

The briefs range from opposing efforts in Maryland to remove a cross-shaped monument on public land to taking on the Democratic attorneys general of New York and Massachusetts, who claim oil giant ExxonMobil defrauded shareholders by downplaying risks of climate change regulation.

With ExxonMobil, Wisconsin joined with Texas and 10 other states in a brief this year, they accused New York and Massachusetts of “unrestrained investigative excursions” of the oil company, and promoting only “one side of an international policy debate.” Wisconsin and the other states argued that “scientists continue to disagree about the degree and extent of global warming and its connection to the actions of mankind, as do many others.”

I hope you're sitting down. Even a D.C. attorney on Schimel's side had to laugh:

Schimel said he worries if Exxon Mobil is found liable for climate change damages, states like Wisconsin could be next. “We provided the infrastructure for all of these vehicles that travel around,” Schimel said. “That liability is too much of a live wire. It’s too unpredictable.”

Several attorneys who have handled climate-related litigation said ...“Wow,” Megan Brown, a Washington, D.C. lawyer who, like Schimel, filed a brief in support of Exxon Mobil. “That’s one of the loonier things I’ve heard.” Road-building involves so many public and private entities, it would be next to impossible to prove global warming was caused by a state, said Brown,

Gov. Scott Walker signed off on Schimel’s brief. Walker didn’t respond to requests for comment.

Of course, Walker wouldn't answer any questions about Schimel's ridiculous reason for joining a lawsuit.
