Koch political advocacy group to ramp up spending in midterms, fight for Dreamers

The Charles Koch-backed political group will spend between $300M and $400M.

Phillips described his work to keep Republicans in office this year as "going against the tide."

He added, "The left is energized. There is no question about that. It is prudent for folks to understand that."

The announcement about campaign spending, interestingly, came at the same time as another wing of Koch's powerful political and philanthropic apparatus voiced disapproval of the White House's new immigration plan.

"Immigration is a good thing," Hooks said plainly during a Q&A session with reporters. He was critical, in particular, of the part of the White House plan that would end a person's ability to sponsor his or her parents or other extended family members. Hooks urged lawmakers to commit to a larger conversation on comprehensive immigration reform.

"We cannot support a policy that arbitrarily reduces the number of people who might come to the country to contribute and ending the family migration policy in the absence of an alternative does that," he added.

Hooks said that the plight of Dreamers should be a top priority for the country, and it would be for the Koch network of political organizations and nonprofits.

When asked by ABC News if they would advise members to vote against a potential bill based off the White House’s framework, Hooks hedged and said only that it was a work in progress and his foundation was lobbying the White House and lawmakers on the issue.

While speaking to a room full of the Koch conference attendees, Tillis spoke highly of the president's plan, including the parts that end what he calls "chain migration."

"We have an opportunity to be the party -– I'm speaking as a Republican -– to be the party that stops talking about fixing the problem and then using it a political as a wedge every election and being the party that solves the problem," Tillis said.

According to Phillips, the eye-popping $300 million to $400 million figure includes $20 million that his organization already spent to lobby in favor of the recent Republican tax bill before it was signed into law at the end of last year, as well as another $20 million it plans to spend in the coming year to try to "sell" Americans on the new reform package.
