he was "horrified" by the events, expressing sympathy for the victims, their families, and first responders; he ordered flags at state buildings lowered to half-staff through the end of the month. Also in October 2018, he opposed a proposal by President Trump to end birthright citizenship in the United States by executive order. In December 2018, Baker called for the suspension of a state district court judge who allegedly assisted an illegal immigrant from being detained by an ICE agent during a legal proceeding from hearing further criminal cases until the federal investigation of the incident is concluded.

In December 2020, Baker signed into law An Act Relative to Justice, Equity and Accountability in Law Enforcement in the Commonwealth, a bill created in response to Black Lives Matter protests calling for police reform across the country in the wake of the murder of George Floyd and the shooting of Breonna Taylor. He originally hesitated to sign the bill and sent it back to the legislature due to a provision that would create a civilian-led commission on police misconduct (six of its nine members would be civilians), saying, "I do not accept the premise that civilians know best how to train police". He also opposed the bill's ban on facial recognition technology. He signed the bill into law after compromising by limiting facial recognition technology, not banning it altogether.

In August 2015, the Coalition of Northeastern Governors under Baker's leadership as vice chair, sent an open letter to acting Food and Drug Administration
