Check out this report from Phil Keating on Happening Now about bogus letters being sent to Florida Republicans in at least 18 counties.

The letters, which appear official at first glance, pretend to be from the office of the Florida supervisor of elections. They state that the recipient's citizenship is in question, and must be cleared up in person before Election Day.

It's believed that the intention is to give the recipient a false impression that they are not eligible to vote.

Authorities are investigating the origin of the letters, which were postmarked in Seattle.
