Meryl Streep has proven, once again, that she is the Queen of Hollywood: she has written to every single member of Congress, demanding equal rights for men and women.

Earlier this year, Meryl Streep followed up her fist-pump moment at the Oscars with several important initiatives towards true gender equality in not only the movie industry, but across the United States.

Streep, who can currently be seen rocking out in Ricki and the Flash, co-stars in the upcoming feminist movie Suffragette — and she seems to be making an increased effort to live up to the early feminist hero she is portraying.

In June, the 66-year-old Oscar-winning actress wrote to all 535 members of U.S. Congress, urging them to revive the Equal Rights Amendment (ERA) written in 1920 and passed in 1972.

The amendment reads, “Equality of rights under the law shall not be denied or abridged by the United States or by any State on account of sex.”

Since the ERA was never written into the Constitution, women in America continue to suffer inequality, both at home and in the workplace. Notably, in 2015 women still earn significantly less than men, with the U.N. reporting a 24% discrepancy between men and women’s earnings.

“I am writing to ask you to stand up for equality – for your mother, your daughter, your sister, your wife or yourself – by actively supporting the Equal Rights Amendment,” Streep wrote in her letter. “A whole new generation of women and girls are talking about equality – equal pay, equal protection from sexual assault, equal rights.”

Earlier in the year, Streep also announced that she was launching a screenwriting lab exclusively for women over 40, combating both the sexism and ageism which plagues Hollywood. The first intake of budding screenwriters were selected in August 2015.
