Hawley portrays himself as someone who can shake up Washington in the video, which features his wife and two kids and the family kitchen as the backdrop.

Hawley set up a fundraising committee over the summer.  He’s been raising money and setting up a campaign team since then.

The Republican will formally announce a campaign to run for the U.S. Senate in 2018 Tuesday morning.
