The Republican senator from Oklahoma said Wednesday he is running for the presidency in 2020 and is using his position to advocate for families that are fighting poverty, including children.

Sen. James Lankford, a freshman from Oklahoma, said he believes that children who are “unwilling to go to work” or live in “extreme poverty” should not be entitled to child support from their parents.

He is the only candidate to speak at the Republican National Convention in Cleveland.

Lankford’s remarks come as the Republican Party is grappling with how to overhaul its welfare system.

He has previously advocated for states to get rid of work requirements and support for families who want to support children.

His position on child support is the latest to raise questions about his willingness to take on the role of child advocate, with Democrats accusing him of pandering to the far-right.

Democrats have slammed the senator’s comments as pandering.

“I’m not a child-support advocate, I’m not an advocate for the working poor, I don’t care if my constituents are in extreme poverty or not,” Lankford said in an interview with The Hill.

“And I’m going to do my part to help my constituents and the working families that they depend on.”

Sen. Jeff Flake, the GOP nominee for the Senate in 2018, is also an advocate, but not for the very poor.

“I’m an advocate of the middle class, and I want to see that we give every American the opportunity to make it,” Flake said during a town hall event in September.

“That’s what I’m about.

I want every American to be able to get ahead.

And so I’m also an American.

I’m an American, but I’m the American who believes in giving people a chance to succeed, because I’m trying to give people a shot.”

He’s also running against Rep. Mike Coffman, a Republican from Colorado who is seeking the Democratic nomination in 2020.

In his interview with the Hill, Lankford described his role as one that “helps the families in our community, and we see them through to a point where they are no longer unable to support their children.”

He said his work includes raising awareness about the economic struggles facing poor families, and also assisting those who are struggling with child support.

Lackford, who is currently the ranking Republican on the Senate Judiciary Committee, was a co-sponsor of a bill that aimed to reform welfare for children.

The bill, which was signed into law in 2016, aimed to allow states to remove work requirements from child support and to allow some of the costs of child support to be paid directly to the family, instead of a court.
