Conservative super PAC drops six-figure ad buy in major move to defend Trump's trifecta

The Sentinel Action Fund, a conservative super PAC focused on Senate elections, will announce the launch of a one-stop voter status registration website following President Donald Trump's State of the Union address on Tuesday geared at keeping GOP voters ready for the midterms.

The group is spending $650,000 to announce the page, which will help visitors determine whether their registration is up-to-date in their state.

Anderson believes voter registration is key to ensuring Republicans have a shot at keeping control of the House and Senate.

"To help support President Trump, voters must mobilize this year and ensure the President continues to have strong partners in the Senate and House. This voter registration tool is designed to help them do just that," Anderson said.

In the past, the Sentinel Action Fund has focused on turning out absentee, early and day-of voters.

Tuesday's ad buy marks the group's first efforts to extend its operations to voter registration.
