Bills have been introduced by Sen. Diane Fienstein (D-CA), Rep. Katherine Clark (D-MA), and Rep. Stephanie Murphy (D-FL).
Of course, it's hardly surprising that female Democratic lawmakers would oppose Trump, especially since that may pay political dividends with enraged progressives. But the only Republican senators to oppose Education Secretary Betsy DeVos were also women: Susan Collins of Maine and Lisa Murkowski of Alaska.
Again, experts insist there are no easy generalizations. But Michele Swers, a professor of American government at Georgetown University in Washington, D.C., said a male-centered dynamic emerged during the campaign that has carried into Trump's administration.
"Trump was very concerned about being the alpha male in the room by trying to feminize his opponents. He called Jeb Bush 'low-energy' and Marco Rubio 'Little Marco,' whereas he's strong leadership. So there's a lot of masculinity in the way they talk about their administration," she said.
Some researchers say women, including women in power, may be particularly unimpressed with such displays of dominance.
"Anybody who has an experience of vulnerability is likely to feel an urgency to act in ways that those with privilege do not, and that for sure includes women," said Juliet Williams, a professor of gender studies at the University of California-Los Angeles.
"People who are in positions of social vulnerability understand the implications of Trump's rhetoric and his polices in a way those not accustomed to seeing themselves as vulnerable don't," she added.
Regardless of whether the efforts of these women pay off in policy change, their bold stance has tremendous impact, Dittmar said. Not only have they positioned themselves to be the first line of defense, they are also setting up the next line.
"It will inspire other women to step up and do the same sort of work to make positive social change," she said. "If we get more women running for office, we get more women who think about themselves being judges or being the future attorney general, that is a huge impact of their work beyond the decisions on any particular policy."
