President Biden’s proposed budget omits mention of the Hyde Amendment, opening the door to publicly funded abortions.

The monster $6 trillion spending plan makes no mention of the amendment, a longstanding budget rider that bars federal funding for nearly all abortions through Medicaid, the military, and other tax-supported programs.

Biden, who is Catholic, was a supporter of the amendment since it was enacted in 1976 — when he was a first-term US senator from Delaware — and included in federal spending bills since then.

But he abruptly reversed himself on the issue at a Democratic National Committee event in 2019, after his presidential campaign took flak from the party’s left wing.

“If I believe health care is a right, as I do, I can no longer support an amendment that makes that right dependent on someone’s ZIP code,” Biden said in 2019.

Advocacy group All* Above All cheered the news. “”We did it!” the group tweeted, “We introduced the budget without Hyde restrictions.”

More than 4,400 Notre Dame University students and alumni signed an open letter this month citing Biden’s Hyde turnabout as reason to exclude him from the Catholic school’s commencement ceremony — which first-term presidents usually attend.

“President Biden today caters to the most extreme voices within his party,” Marjorie Dannenfelser of the anti-abortion Susan B. Anthony List said.

A January Marist/Knights of Columbus poll found that 58 percent of Americans oppose the use of public funds to pay for abortion.
