CHICAGO — In a prime-time speech overlooking the U.S. Capitol, Illinois U.S. Sen. Tammy Duckworth seized her high-profile moment at the Democratic National Convention on Thursday by launching an offensive against President Donald Trump for politicizing the military and displaying failed leadership abroad.

The double amputee and Purple Heart recipient labeled Trump as America’s “coward in chief,” painting him as selfish and weak while portraying Democratic presidential nominee Joe Biden as a man of decency and integrity.

Duckworth said Biden “knows the fear military families live with because he’s felt that dread of never knowing if your deployed loved one is safe” after his late son, Beau, deployed to Iraq.

“That’s the kind of leader our service members deserve: one who understands the risks they face and who would actually protect them by doing his job as commander in chief,” Duckworth said. “Instead, they have a coward-in-chief who won’t stand up to Vladimir Putin, read his daily intelligence briefings or even publicly admonish adversaries for reportedly putting bounties on our troops’ heads.”
