LAWRENCE, MASS. -- Several Massachusetts lawmakers threw their support behind U.S. Sen. Elizabeth Warren’s White House run Saturday, arguing that she’s the best Democrat to take on incumbent President Donald Trump in 2020.

U.S. Sen. Ed Markey, D-Massachusetts, and U.S. Reps. Joe Kennedy III, D-Newton, and Lori Trahan, D-Westford, were among the state officials to take the stage to rally supporters who gathered in Lawrence for Warren’s 2020 campaign kickoff.

Markey said he was “honored” to help his U.S. Senate partner launch her White House run, offering that he has watched her fight for working class Americans throughout their time together in Congress.

“I’ve been in Congress for awhile now and no one, no one knows how to fight for what is right better than Elizabeth Warren," he said. "And these days, fighting for what is right means fighting the dangerous, divisive, hateful agenda of Donald Trump."

Markey, however, added that “no one know how to get under Donald Trump’s skin better than Elizabeth Warren.”

Pointing to her work on Wall Street regulations and as a member of the U.S. Senate, Kennedy argued that Warren is the one candidate in the 2020 race who has dedicated her life to fighting for working class Americans.

“I am here with you today because this country needs a leader who will restore the solidarity that Donald Trump stole. Who won’t cower from the big, tough battles, from the ugly injustice and oppression that still finds its way to American soil,” he said. “A leader will bring this country together to take on our greatest common threat: a system that protects the powerful and privileged while the rest struggle to scrape by. That leader is my colleague, my mentor, my friend: Elizabeth Warren."

Contending that the stakes of the 2020 election “could not be higher,” Trahan, meanwhile, said it’s critical the country selects a president who acknowledges that while the economy may work well for the wealthy, it’s not working for most Americans.

That type of champion, she said, “is someone like Elizabeth Warren.”

“Elizabeth will put her finger on the scale for working families --not banks, not multi-national corporations, and not those who can afford to give millions of dollars to political candidates,” she said.

Trahan further offered that Americans “could count on a President Warren to wake up each and every day and put the needs of the American people at the forefront of our policy debate and that real and enduring and significant change.”

“Elizabeth has proven time and again that she is up to the challenge and I am proud to be with her in this fight,” she said.

Warren formally launched her 2020 presidential campaign during a late-morning event outside the Everett Mill in Lawrence -- the site of the 1912 “Bread and Roses” labor strike.

The Massachusetts Democrat, who formed a presidential exploratory committee in late December, used the event to make her case to American voters and lay out her vision for a country that prioritizes working and middle-class people over the wealthy and well-connected.
