Just a few days before D.C. leaders will speak before Congress about a D.C. statehood bill, the statehood cause gained a famous new supporter: Alyssa Milano.

The actress, activist and philanthropist tweeted her support of D.C. statehood to her 3.7 million followers on Tuesday.

D.C. deserves statehood: now.

I am proud to work with @51for51 to fight for #DCStatehood and #HR51 💪🏾

— Alyssa Milano (@Alyssa_Milano) March 16, 2021

Milano is best known for her starring role on the Y2K-era hit television show “Charmed” and her ensuing years of progressive activism. She champions a wide range of causes, including the #MeToo movement, transgender rights, gun violence prevention, and Democratic politicians like President Joe Biden.

She’s not the only big name to push for D.C. statehood recently.

Christian Cooper, the birder who was accosted by a white woman in Central Park last summer after asking her to leash her dog, wrote a Washington Post op-ed last month urging Senate Democrats to scrap the filibuster and pass a D.C. statehood bill.

“The Democrats have a historic opportunity to associate themselves with pure joy in the streets of Washington, D.C.,” he told DCist/WAMU. “I can’t see how how people wouldn’t leap at this.”

Like Milano, Cooper is working with 51 for 51, an advocacy group focused on statehood and ending the filibuster.

Milano is speaking on behalf of D.C. at a time when passing a statehood bill feels more likely than ever. Democrats control the House, Senate and White House — and Biden is on the record with his support for statehood.

Many Democrats are prioritizing the cause as a top civil and voting rights issue in the wake of the racial justice protests last summer, disputes over the 2020 election and the federal government’s response to the insurrection at the Capitol in January.

On Monday the House Committee on Oversight and Reform will hold a hearing on the D.C. statehood bill H.R. 51. The bill passed the House in a historic vote last June, but died in the Senate. (Republicans in that chamber remain almost uniformly cold to statehood; they also retain the power of the filibuster to block any bill.) D.C. Delegate Eleanor Holmes Norton reintroduced the bill on the first day of the new Congress in January.

Statehood has long garnered overwhelming support among District residents and officials: 86% of Washingtonians voted in favor of becoming the 51st state during a 2016 referendum. (It has also gained more national support over the years, largely among Democrats.) Mayor Muriel Bowser will make the case for H.R. 51 in front of the House committee next week.

A few other actors have supported statehood over the years, if only briefly. Hayden Panettiere lobbied on the city’s behalf in 2015. Mario Van Peebles and Evan Handler (a.k.a. Charlotte’s lawyer-turned-hubby Harry Goldenblatt from “Sex and the City”) created pro-statehood PSAs. And William Baldwin, Elizabeth Banks and other stars appeared at a D.C. voting rights luncheon during the 2016 Democratic National Convention.
