Miller, Lee Introduce Bill To Protect Student Data From Far-Left Voter Operations

Today, Congresswoman Mary Miller (IL-15) introduced the Student Voter Data Protection Act to protect college students’ personal information from being shared without their consent for partisan voter registration efforts.
“The Student Voter Data Protection Act puts a hard stop to Left-wing data harvesting, making student data strictly opt-in and cutting off the pipeline to non-consensual personal information.”

Campaign money

Method

In the 2025–26 cycle Miller’s campaign raised $1.3M: $1.2M (87%) from individuals and $145K (11%) from PACs and other committees. Cash on hand: $810K.

Through Jun 30, 2026; filings lag, so recent gifts can take weeks to appear. Money raised also counts loans and transfers, so the shares need not add to 100%. Source: FEC.gov.
