Massachusetts Senate President Karen Spilka issued a scathing denunciation of President Donald Trump Monday in a speech pegged to Trump’s first 100 days in office, saying she sees the United States entering a “dark chapter” that’s rendering the country unrecognizable.

“I for one, my friends, cannot sit idly by as we hear story after story, day after day, of residents being grabbed off the streets, kidnapped, and held with no access to justice,” Spilka said, citing the recent detentions of Rümeysa Öztürk in Somerville, Juan Francisco Méndez in New Bedford, and Kseniia Petrova at Logan Airport as examples.

“As someone who lost family members to the Holocaust, I do not say this lightly, but what we are experiencing in America today is starting to feel like Europe in the 1930s,” Spilka continued. “And it’s not just terrifying, it is enraging.”

Spilka went on to call the Trump administration “capricious, vengeful and cruel,” saying the president and his allies have “co-opted federal law enforcement agents and openly defied the courts.”

Tuesday marks the 100th day of Trump’s presidential term.

Spilka described her speech Monday as part of Response 2025, the Democrat-dominated state Senate’s ongoing effort to respond to what it sees as the dangerous excesses of the Trump administration.

“Let it be entered into the record today that I unequivocally object to the dissolution of due process and the rule of law in America,” Spilka said. “And as long as I am Senate president, Massachusetts will resist this new tyranny.”

After a long standing ovation, Spilka’s fellow senators offered similar denunciations of President Trump, and his approach to immigration and governance generally.

After calling for increased funding to support Attorney General Andrea Campbell’s litigation against the Trump administration, state Sen. Barry Finegold urged his colleagues to pursue more policies aimed at stemming the outflow of population from Massachusetts to red states, warning that failure to do so will place Democrats in an untenable position in future presidential elections.

“We have to find ways ... like we’ve already started to, of keeping young people here in the commonwealth,” Finegold said. “We can’t afford to lose another congressperson. We can’t afford for our [members of the] Electoral College to go to some other state.”

Other senators offered terser assessments of the current political moment.

“We have emboldened a new generation and a new group of people who find it OK to be hateful, because the person at the top has given them full authority to do so,” state Sen. Sal DiDomenico said.
