This bill increases penalties for forging or counterfeiting U.S. postmark stamps, particularly when used on mailed ballots in federal, state, or local elections. Currently, forging a postmark can result in a fine and up to five years in prison, but this legislation would increase the maximum prison sentence to ten years if the forged postmark is applied to a mailed ballot. The bill also creates a new offense for someone who applies a genuine postmark bearing an incorrect date to a mailed ballot with the intent to falsify when it was sent, subjecting violators to the same ten-year penalty. The legislation targets election-related mail fraud by making it a more serious crime to tamper with postmarks on ballots specifically. No specific funding or implementation timeline is mentioned in the bill.
