Senator to keep pushing broader gun checks – One of the principal sponsors of defeated gun background check legislation said he isn’t giving up on getting a bill passed. West Virginia Democratic Sen. Joe Manchin said backers of expanded background checks for gun purchases must focus on “where the comfort zone is” with gun owners. A bill Manchin co-sponsored with Republican Sen. Pat Toomey of Pennsylvania failed to clear the Senate last month. The National Rifle Association, which staunchly opposed the measure, celebrated its defeat at a convention in Houston.
