"The map shows something powerfully important: a strong grassroots movement is ready to fight back & make real change for MA & our country," Warren tweeted.

Warren has been a strong critic of President Trump since his presidential campaign.

Last week, she slammed the president after he sent a letter to Congress explaining his reasoning for launching an airstrike on Syria.

She said in a series of tweets she saw "no compelling strategic justification" for the strike and called the president's approach to Syria "erratic."

A recent Morning Consult poll found Warren had a favorability rating of 56 percent.
