Efforts are underway to protect abortion rights as nation adjusts to Supreme Court's reversal of Roe v. Wade - CNN

Wade was felt immediately, with at least 10 states effectively banning abortion as of Saturday night.

Alexandria Ocasio-Cortez has raised an estimated $400,000 for abortion rights groups -- including tens of thousands during a widely-viewed Instagram Live late on Saturday evening, a spokeswoman told CNN.

Ocasio-Cortez, on NBC's "Meet the Press" Sunday morning, also suggested President Biden expand access to abortion by a variety of means, including the opening of clinics on federal lands inside states that have or plan to enact bans, and to use the tools of the executive and federal agencies to help make medical abortion, through pills obtained via the mail, more easily accessible.

Elizabeth Warren offered a similar plan of action during an interview with ABC's "This Week," saying the federal government should consider every available legal path to mitigate the new bans and aid states where women are expected to travel to seek legal abortions.

Advocacy groups, meanwhile, are pressing ahead with new legal arguments within the states -- in some cases digging into their own laws for potential avenues to slow or upend new restrictions.

In Utah, which is among the states that moved quickly to ban most abortions following Friday's ruling, Planned Parenthood has already filed a lawsuit against the state's top leaders, claiming its newly enacted law violates multiple civil liberties codified in the state's constitution.

Performing an abortion in Utah under its ban is now a second-degree felony in nearly all cases, according to the lawsuit, which names the governor and the attorney general among the defendants.

(The Utah law allows for abortion in three circumstances -- where there is danger to the mother's health, uniformly diagnosable health conditions detected in the fetus or when the mother's pregnancy is the result of rape or incest.)

The lawsuit argues the new abortion law violates multiple rights protected under Utah's constitution, such as the right to determine family composition and equal protection rights, among others.

Tony Evers vowed to "fight this decision in every way we can with every power we have," after his Republican-controlled state legislature declined to repeal the state's 1849 law banning abortion, which is taking effect again following the Supreme Court ruling.

"Our office is reviewing today's decision and will be providing further information about how we intend to move forward next week," Wisconsin Attorney General Josh Kaul said in a statement Friday.

Protesters arrested during demonstrations

Demonstrators both for and against the High Court's decision have been taking their voices to the streets this weekend in small towns and big cities across the nation, with more events planned Sunday.

No further details were provided on the arrests.

On Friday night in Phoenix, law enforcement used tear gas to disperse a crowds of protesters who were demonstrating in front of the State Senate.

Protecting reproductive rights

As some states move to restrict abortion rights, others are taking steps to better protect and expand abortion access and funding.

Tim Walz issued an executive order Saturday providing protections for people who travel into the state for reproductive health care from states where abortion is illegal or criminalized, his office said.

North Dakota is one of many states that have trigger laws on the books aiming to ban abortion following the Supreme Court ruling.
