That above bill, SB-2099, was introduced in Feb 2000. so the original post is fiction. Thank God!!!
HR-45-Blair Holt's bill is real, but stands no chance of passing to law. From what I gather.
H.R.45 - Blair Holt's Firearm Licensing and Record of Sale Act of 2009
OpenCongress Summary
The Blair Holt's Firearm Licensing and Record of Sale Act would establish a nationwide system for prohibiting unlicensed gun-ownership. If approved, the law would require gun owners to apply for five-year licenses to own firearms, and would give the U.S. Attorney General broad authority over the program.
This is a fringe bill with no co-sponsors that has virtually zero chance of becoming law. For more background on why there are bills in Congress like this one that are essentially dead on arrival.
