Without saying the business mogul’s name, President Barack Obama took a jab at Republican presidential candidate Donald Trump on Monday, saying he’s tired of people “trash talking America’s military and troops.”

WhiteHouse.gov Obama is not amused by criticism of the U.S. military from people like Donald Trump.

“Let’s get some facts straight. America’s Army is the best-trained, best-equipped land force on the planet,” Obama said while speaking at the Disabled Veterans Convention in Atlanta, Georgia.

The president emphasized that “no one ― no one ― has given more for our freedom and security than our Gold Star families,” referring to those whose loved ones have died fighting in the United States military. That includes Khizr and Ghazala Khan, the parents of Army Capt. Humayun Khan, who was killed in Iraq in 2004.

Khan criticized Trump while speaking at the 2016 Democratic National Convention, saying Trump has “sacrificed nothing.” Trump responded by claiming he’s “made a lot of sacrifices” in order to create jobs, tweeting that he was “viciously attacked” by Khan.

While many have praised the actions of Humayun Khan, his father has been smeared as a terrorist for speaking out against Trump.

Editor’s note: Donald Trump regularly incites political violence and is a serial liar, rampant xenophobe, racist, misogynist and birther who has repeatedly pledged to ban all Muslims — 1.6 billion members of an entire religion — from entering the U.S.
