Democratic National Committee chairman Tom Perez said Friday that all Democrats who run for political office must support a "women's right to choose" — which really means be pro-abortion.

Perez said in a statement, according the Huffington Post:

Every Democrat, like every American, should support a woman’s right to make her own choices about her body and her health. That is not negotiable and should not change city by city or state by state. At a time when women’s rights are under assault from the White House, the Republican Congress, and in states across the country,” he added, “we must speak up for this principle as loudly as ever and with one voice.

Perez added in a series of tweets that when he ran for DNC chair, he promised to fight for abortion rights.

The statements come amid some controversy surrounding Heath Mello, a Democratic candidate for mayor in Omaha, Nebraska. Mello, it was recently discovered, had for years fought against abortion, leading many pro-abortion organizations to rebuke him last week.

Perez initially defended the DNC's support of Mello, saying in a statement that his job is to help Democrats who have garnered support to "cross the finish line and win" in elections and that the "biggest threat" to abortion rights is the GOP.

However, Perez changed his tune on Friday with his statement about abortion rights being an issue that all Democrats must support. Perez also said that he "fundamentally disagrees" with Mello's position on abortion rights and reiterated that "every candidate who runs as a Democrat should do the same, because every woman should be able to make her own health choices," according to the Huffington Post.

Republicans, of course, take issue with this hardline abortion stance. But Sen. Ben Sasse (R-Neb.) had just one quick question for Perez on Sunday.

Writing on Twitter, Sasse noted that Perez's Twitter bio says he is "fighting for the little guy." So Sasse decided to test the limits on just which "little guys" Perez is fighting for.

Tweeting a picture of a 12-week-old unborn baby, Sasse wrote: "Your profile says you fight for the little guy. Please check out this little fella -- special, isn't he? (He's 12 weeks old.)"

Perez has not yet responded to Sasse's tweet.
