McCain To Renew Effort for Gun Show Bill U.S. Sen. John McCain (R-AZ) has announced his intentions to force a Senate vote early next year on legislation that would require criminal background checks on all firearms sold at gun shows. The effort is driven by allegations by gun control advocates claiming that foreign terrorists can easily obtain firearms from private sellers who are not required under federal law to conduct the checks. According to a press report in USA TODAY (Nov. 27), McCain, with the backing of Senators Mike DeWine (R-OH), Joe Lieberman (D-CT), and Charles Schumer (D-NY), will likely attach a gun show bill as an amendment to another piece of legislation, “probably a homeland security measure,” when the Senate convenes in January.
