A 600-page immigration plan presented by White House senior adviser Jared Kushner seeks to unifying the Republican Party for 2020 and position it as the "party of legal immigration," The Hill reported Wednesday.

"It's important that Republicans be for something and not against something, and the president has worked hard to design this plan and we want to make sure we can all be unified as a party," Kushner told Senate Republicans in a Wednesday meeting, per The Hill source.

Kushner unveiled the package designed to put a positive stamp on the GOP immigration reform efforts vs. the open-border policies of Democrats in the 2020 campaigns.

"I didn't hear any negatives," Senate Homeland Security and Governmental Affairs Committee Chairman Ron Johnson, R-Wis., told The Hill. "You heard certain suggestions. Nobody is going to agree on everything.

"People do recognize that in order to pass something you're going to have to eventually be discussing and add different elements, but I'd much rather do one step at a time and concentrate on something we hopefully can agree on."

The GOP message for 2020 needs to position itself as a positive influence on legal immigration reform, strengthening border security and moving more toward a merit-based immigration system, according to Kushner.

"This is a pretty good first step," Johnson told The Hill.

Kushner also reportedly told attendees the Trump administration plans to have between 400-500 miles of border wall built by the end of 2020, noting the drop in border apprehensions and praising the work of Acting Department of Homeland Security Secretary Kevin McAleenan, per The Hill.

"It's important for us to talk about what we're for when it comes to immigration," Senate Republican Steering Committee Chairman Mike Lee, R-Utah, told The Hill after the meeting he set up, introducing Kushner himself.
