This past week was a real test of Joe Biden’s staying power as one of the Democratic Party’s 2020 presidential front-runners.

Between two votes from his Senate career coming back to haunt him and a handful of cringeworthy moments, the former vice president saw increased pressure to address his biggest weak spots.

Here’s a look at his most notable moments from the past week.

Support For The Hyde Amendment

Biden spent much of the past week coming under fire for supporting the Hyde Amendment, a 1976 provision that restricts federal funding for abortions and that the former vice president voted for when he was a senator. Before reversing course later in the week, his campaign reiterated his support for the controversial policy on Wednesday.

Biden “has not at this point changed his position on the Hyde Amendment,” his campaign told HuffPost, and contended that “the Hyde Amendment does not prevent organizations in the U.S. that provide lifesaving health care services for women from receiving the federal funding they need.”

Because the provision bans Medicaid, Medicare and other federal health insurance programs from covering the vast majority of abortions, low-income women and women of color are disproportionately affected by it. Democrats and other 2020 candidates quickly slammed Biden for standing by such a policy.

“It’s been the law for a while, and it’s been wrong for a long time,” his opponent Sen. Elizabeth Warren (D-Mass.) said. Sens. Kirsten Gillibrand (D-N.Y.), Bernie Sanders (I-Vt.) and Kamala Harris (D-Calif.) ― three others in the Democratic 2020 field ― also spoke out against the Hyde Amendment following his campaign’s comments.

By Thursday, Biden had changed his tune.

“I can’t justify leaving millions of women without the health care they need. ... If I believe health care is a right, as I do, I can no longer support [the amendment],” he said.

The Iraq War Vote

While progressives welcomed Biden’s reversal on the Hyde Amendment, the incident shed light on another hot-button issue from his past: his 2002 vote to give then-President George W. Bush the authority to invade Iraq.

In a tweet Friday, Rep. Seth Moulton (D-Mass.) applauded and criticized Biden in the same breath.

“Now do the Iraq War,” he said, calling on Biden to say he erred in voting for the controversial war.
