WASHINGTON ― Sen. Mazie Hirono (D-Hawaii) said Wednesday that she was dismayed by Joe Biden’s support for the Hyde Amendment ― which bars federal funding from going toward abortion procedures.

“I find it personally disappointing that he doesn’t make it very, very plain that he is behind a woman’s right to choose as a constitutional right,” Hirono told HuffPost on Wednesday when asked about the stand taken by the former vice president and 2020 Democratic presidential candidate.

Biden’s campaign reiterated his support for the amendment, which he voted for as a senator in 1976, earlier Wednesday in a report by NBC News. A Biden campaign aide told HuffPost that he would be open to repealing the Hyde Amendment if a woman’s “protected rights under Roe v. Wade are closed.”

Biden’s reaffirmation of support for the Hyde Amendment immediately drew comments from other 2020 Democratic hopefuls, including Sens. Elizabeth Warren (D-Mass.), Kamala Harris (D-Calif.) and Kristen Gillibrand (D-N.Y.), who made it clear they support repealing the amendment. But most of Biden’s Democratic challengers refrained from directly calling out on the matter.

“I’m not going to tell him what to do,” Harris told HuffPost on Wednesday when asked if Biden ought to change his position. But, she added, she’d “never be in favor of a policy that denies women access to health care.”

Earlier this year, Hirono helped introduce a bill to repeal the Hyde Amendment and lift the prohibition in current law preventing women who receive their health coverage through government-sponsored plans, such as Medicaid and Medicare, from obtaining an abortion. The bill was supported by nearly all the female Democratic senators, including Tammy Duckworth of Illinois and Jeanne Shaheen of New Hampshire. But they, too, approached the matter cautiously on Wednesday by noting only where they stand on the issue.

“I think we will see nominees take various positions around Roe v. Wade. All will support the underlying need to protect Roe v. Wade,” Shaheen said.

Sen. Dianne Feinstein (D-Calif.), a Biden supporter who also co-sponsored legislation to end the Hyde Amendment, similarly gave the vice president a pass.

“I think this is up to him. He’s a man of faith, and that faith is well deserved. He’s had a lot of tragedy in his life,” she said.
