Donald Jr. on pay gap

According to the U.S. Census Bureau. Income, Poverty, and Health Insurance Coverage in the United States report back in 2012, women earn 77 cents to every dollar that their male counterpart makes in the world-place. Various factors cause the result, with many on the left alleging sexism, while conservatives point to the choice in career of many women, which has caused a heated debate in American politics in recent years.

While Donald Trump vowed to be a great president for all women during the 2016 presidential election, the majority of females in the United States have pushed back, which was evident during the women's march that took place not long after his inauguration. Fast forward to present day and the president is struggling to appeal to the masses. Though his base continues to show their support, Trump's approval rating has dropped to just 40 percent, with his favorability with women sinking even lower. As seen on his Twitter account on July 3, Donald Jr. decided to take a shot [VIDEO] at the gender pay gap.
