Americans for Prosperity, a conservative group backed by GOP mega-donors Charles and David Koch, plans to launch a six-figure campaign in 2018 to support President Trump's judicial nominations in as part of its new plan to ramp up judicial engagement.

The group will be laying the groundwork for the next vacancy on the U.S. Supreme Court and plans to engage on nominations to federal district and appeals courts. Americans for Prosperity also announced it has hired Sarah Field, the former deputy director for state courts at the Federalist Society, to lead its new judicial engagement efforts as its vice president of judicial strategy.

As part of their grassroots efforts, the organization will educate activists in 36 states in preparation for a vacancy on the high court. It will also mobilize its activists to reach out to lawmakers on Capitol Hill to push for the confirmations of lower court nominees, and for confirmation hearings to be held, a spokeswoman for Americans for Prosperity told the Washington Examiner. The group plans to launch digital ads and hold tele-town hall meetings with senators, as well as different events, in support of nominees to the federal bench, the spokeswoman said.

The network invested six figures in judicial engagement in 2017, and will make a larger investment this year, although the group didn't say how much more funding is available this year for Americans for Prosperity. The spokeswoman said Americans for Prosperity plans to fill a "market gap" by taking a "grassroots approach" to judicial confirmations.

“Securing Justice Neil Gorsuch onto the Supreme Court bench was a major victory for freedom, but the fight to realign our courts around the rule of law is far from over,” Field said in a statement. “With over 170 vacancies on lower courts across the country, America is facing an urgent judicial crisis. Everyday Americans are not able to access the justice guaranteed to them by our Constitution because of these vacancies.”

Concerned Veterans for America, a partner organization to Americans for Prosperity, led efforts last year backing Gorsuch’s confirmation to the Supreme Court, as well as confirmations to the lower courts. The group made more than 500,000 phone calls, launched online ads in 12 states, and backed three waves of direct mail and digital ads in support of Gorsuch’s nomination.

Americans for Prosperity plans to build on those efforts this year.

“We saw last year how passionate Americans are about ensuring fair and qualified judges are confirmed — they know that at its core, this fight is about protecting the rule of law,” Field said. “This year we will mobilize our activists as needed, particularly when members of the Senate choose to needlessly obstruct the confirmation process.”

President Trump inherited more than 100 lower court vacancies when he assumed the presidency. In 2017, the Senate confirmed 12 of the president’s nominations to the federal appeals courts, the most of any president during his first year in office.

According to the Administrative Office of the U.S. Courts, there are currently 145 judicial vacancies.

Though there are no open seats on the Supreme Court, there has been speculation surrounding Justices Ruth Bader Ginsburg and Anthony Kennedy’s futures. Ginsburg is 84 and Kennedy is 81, but neither have indicated they’ll retire.

Ginsburg has hired law clerks through 2020, and Kennedy has hired clerks for the October 2018 term, according to Above the Law.
