Fact check: Heath Mello’s voting record on abortion

Conclusion

Former Nebraska state Sen. Heath Mello, the Democratic candidate in Omaha’s mayoral race, was joined at an April 20 campaign rally by DNC Chair Keith Ellison, Sen. Bernie Sanders (I-Vt.), and Nebraska Democratic Party Chair Jane Kleeb.[1] That elicited a critical response from Ilyse Hogue, the president of NARAL Pro-Choice America, who characterized Mello as an “anti-choice candidate” and said the Democrats’ embrace of him was “politically stupid.”[2]

During his time in the Nebraska Senate, Mello voted for three bills that put restrictions on abortion.[3][4][5] Mello also voted to bar health insurance plans offered through state-run exchanges from covering abortion; to require that, if an ultrasound is performed prior to an abortion, its images be displayed; and to require that women undergo screening for various risk factors before the procedure.[8][6][7]
