Days after federal agencies warned of a heightened threat of violent attacks on political candidates, an extremist gun rights group on Monday urged supporters to give it money so it can figure out how much firepower we have to unload on gun-grabbing candidates in Senate races in key battleground states.

At midnight tomorrow, well know exactly how much firepower we have to unload on gun-grabbing candidates in AZ, NV, GA, PA and OH as we head into next weeks election day, reads a fundraising email from the American Firearms Association.

The email from the group, whose president casually mentioned in another recent fundraising email that he was under FBI investigation , says it is falling short of what it hoped to raise for its U.S. Senate Second Amendment Ad fundraising blitz.

Were looking for 411 of our AFA supporters to ... give us all the resources we need to drive the final nail into Joe Bidens gun control agenda! reads the email. It directs supporters to an angry-looking photo of Biden and asks for a minimum donation of $17.76, a reference to the year 1776, the year of the American Revolution.
