Paul D. Clement, a former U.S. solicitor general and one of the country’s foremost litigators, is working once again with the National Rifle Association in an effort to get the largest gun lobby to write an amicus brief in the lawsuit filed by Sandy Hook families.

The conservative-leaning Clement, who’s been a go-to attorney for the NRA on Second Amendment issues, is looking to represent the association as an amicus curiae in the lawsuit pitting several families of Sandy Hook victims against two gun manufacturers. The NRA’s request to file an amicus brief is pending before the Connecticut Supreme Court.
