NASHVILLE (AP) - The House sponsor of a bill seeking to do away with permit requirements to openly carry is offering to raise the estimated $100,000 cost from private sources.

Republican Rep. Micah Van Huss said in a letter to his House colleagues on Monday that he was disappointed with what he called a "bogus" cost estimate attached to the bill that he sees as an attempt to kill the measure.

The bill would eliminate the state's background and training requirements for openly carrying guns in public. It would keep the permit rules in place for concealed firearms.

The Senate passed its version of the bill on a 25-2 vote last week. Van Huss wants to pull the bill up for a floor vote without waiting for it to clear committees.
