Wrap: Sen. Joseph Keaveny says he thinks momentum changed in the fight over a bill that would make it a crime for law enforcement officials to enforce some federal gun laws. 

After Missouri House Speaker Tim Jones announced his support for the veto override, Keaveny says says he's not sure Jones has the support he needs.

Jones issued a statement attacking the Attorney General's letter suggesting that police could face criminal penalties for enforcing gun laws under the bill.
