Trump Jr. takes a cheap shot at Greta Thunberg for being Time's Person of the Year over his dad

Donald Trump Jr. isn't impressed with 16-year-old activist Greta Thunberg being selected as Time's Person of the Year in 2019.

Other finalists for the job included his dad, President Trump, along with Speaker of the House Nancy Pelosi, and the Hong Kong protesters.

Trump Jr. even took a cheap shot by suggesting she was being "used."

"Time leaves out the Hong Kong Protesters fighting for their lives and freedoms to push a teen being used as a marketing gimmick. How dare you?" the eldest Trump son declared.

Greta gained international fame after her protests against climate change inaction. She started from the very bottom, organizing as a one-person protest in her native country of Sweden and growing into marches all around the world.

Time's editor-in-chief Edward Felsenthal called Thunberg the "biggest voice on the biggest issue facing the planet."

“She also represents a broader generational shift in the culture that we’re seeing from the campuses of Hong Kong to the protests in Chile to Parkland, Fla., where the students marched against gun violence ,where young people are demanding change urgently,” he said.

Trump Jr. also found his way in the news on Wednesday by reportedly shooting and killing an endangered sheep while on a hunting expedition in Mongolia. Hunters in the country need to get permits in order to do so, but he allegedly didn't get one until after the hunting.

The president's son killed a majestic long-horned argali sheep while on the trip that he purchased while at a National Rifle Association fundraising benefit.

The argali sheep is known as the largest species of sheep in the world and by its distinctive curved horns.

Trump Jr. met with Mongolia's president in the capital of Ulan Bataar, and maybe that's one reason he received special treatment from Mongolian officials.
