In 2017 Pingree did not attend the inauguration of Donald Trump and instead visited a Planned Parenthood center and a business owned by immigrants. She attended the Women's March on Washington the following day and stood on stage with other politicians who had also refused to attend the inauguration. “We need to do everything we can to let the incoming administration know we are not happy about their agenda. I’ve had unprecedented numbers of my constituents calling me worried about healthcare, the environment, public education, and they feel disrespected,” she said. In July 2019, Pingree joined 95 Democrats voting for a Trump impeachment resolution. Maine representative Jared Golden and 136 other Democrats joined with their Republican colleagues to kill the resolution.
