TOPEKA, Kan. (AP) — Kansas’ secretary of state says he’s serving on President-elect Donald Trump’s transition team.

Kris Kobach, a conservative Republican, told various Kansas media outlets Wednesday he has no expectation of a role in Trump’s eventual administration. But he says he’s open to working for Trump, if offered.

As part of his unpaid role with the transition team, Kobach will help advise Trump on policy matters leading up to his January inauguration.

Kobach previously advised Trump on immigration policy during the campaign, successfully adding to the Republican Party’s platform Trump’s plan to build a wall along the U.S.’s southern border with Mexico.

Kobach also has served as counsel to Attorney General John Ashcroft during the President George W. Bush’s administration.
