A veterans advocacy group has slammed U.S. Sen. Elizabeth Warren, calling her “Aleppo Liz” and accusing her of putting illegal immigrants ahead of Americans who served their nation in war.

“Today marks the twentieth day since Veterans Assisting Veterans (VAV) open letter to all American’s was first published. … It also marks twenty days of silence from every member of the United States Congress and Senate,” the open letter from John MacDonald of Lowell-based Veterans Assisting Veterans states. “Not one of our elected leaders has felt the need to share where they stand. We ask Senator Elizabeth Warren, Senator Edward Markey and the Massachusetts Congressional delegation … do you stand with us or against us?”

MacDonald’s letter claimed the group has received “countless calls and messages from veterans around the country. Many of them are veterans who have experienced devastating issues and lack of attention from Veterans Administration (VA) Hospitals across the country … All of them have said that our elected officials should put veterans ahead of illegal immigrants.”

MacDonald said the issue has reawakened old wounds for Vietnam vets — particularly when some Democrats failed to stand for the widow of a fallen Navy Seal, Chief Petty Officer William “Ryan” Owens, during an emotional moment in President Trump’s first joint House and Senate address.

“The Vietnam Veterans had ‘Hanoi Jane Fonda’ that provided comfort to our enemies during the Vietnam War. Today the War of Terror, illegal immigrants and refugees that are tearing down the foundation of civilized society here in the US, Europe and abroad now we have ‘Aleppo Elizabeth Warren’ standing with them and against all of us.

“‘Aleppo Liz’ is leading the way to thumb her nose at America and Americans by providing comfort to anyone other than the American Citizen and our US Veterans. Those elected officials that support her stance and lack of understanding between illegal immigrants and those who are legally waiting in line is shameful and rife with their own self-interest,” the letter states.

A Warren spokeswoman has said the well-being of veterans is of “utmost importance” to the senator, and that she wants to ensure they received benefits and services they deserved, but the spokeswoman said Warren would do that while also criticizing Trump’s immigration policies.
