(Adrees Latif/Reuters)The three remaining presidential candidates spent Memorial Day honoring U.S. military service members, each in their own unique way.

In Chappaqua, N.Y., Hillary Clinton marched in the town’s annual Memorial Day parade with former President Bill Clinton, New York Gov. Andrew Cuomo and a large contingent of Secret Service agents.

“Our fallen heroes deserve our profound gratitude for giving their lives to protect our freedom,” she wrote. “Today and every day.”

But the Vermont senator also took the opportunity to tweak Donald Trump, who vowed to “rebuild our military” and “knock the hell out of ISIS” at the Rolling Thunder rally in Washington, D.C., Sunday afternoon.

https://s.yimg.com/os/yc/html/embed-iframe-min.0d1dfd9e.html“It’s easy to give speeches about how tough we are,” Sanders tweeted, “but let us not forget the cost of war on the men and women who serve in our military.”

After firing off a series of early-morning tweets thanking the Border Patrol union for its endorsement, Trump did something unusual, at least for him: He appeared to sign off from Twitter for the day.
