Pop star Halsey is mobilizing their fans against the impending threat to abortion protections in the U.S., saying we all have the right and responsibility to fight this in a passionately worded plea on Tuesday.

The 27-year-old singer joined a handful of celebrities, including Amy Schumer , Phoebe Bridgers and more, expressing outrage over the leaked draft of a Supreme Court opinion that would end the constitutional right to abortions by overturning Roe v. Wade.

Reversing the landmark 1973 decision would result in a catastrophic shift in our fundamental rights to bodily autonomy and reproductive health care, Halsey wrote, encouraging their followers to immediately take action.

This is one of the most significant events we will witness in our lifetimes, they continued, noting that the draft is not hypothetical after Chief Justice John Roberts confirmed the leak. The effects of this decision will spiral into lethal situations for our entire country. Most seriously impacting people of color, rural areas and socioeconomically impacted communities.
