Former NFL quarterback Colin Kaepernick received criticism after he spoke out about what he called “American terrorist attacks” against people of color. On Saturday, Kaepernick added to the chorus of criticism of President Donald Trump’s decision to order the airstrike that killed Iran’s top general -- Qassem Soleimani. In pair of tweets on Saturday, he said, “There is nothing new about American terrorist attacks against Black and Brown people for the expansion of American imperialism." https://twitter.com/Kaepernick7/status/1213552939786096640 https://twitter.com/Kaepernick7/status/1213553331181764608 His tweets did not sit well with some Twitter users: https://twitter.com/SebGorka/status/1213834211863547904 https://twitter.com/MarkDice/status/1213570063275417600 https://twitter.com/megynkelly/status/1213603362605658112 https://twitter.com/GPIngersoll/status/1213846427044106240 https://twitter.com/robbystarbuck/status/1213601985431326725 Kaepernick’s tweet comes amid escalating tension between the United States and Iran that led to the decision to target Soleimani -- who was believed to be planning some kind of attack against America. Trump authorized an airstrike on Thursday to kill Soleimani after an Iranian backed militia attacked an Iraqi military base where U.S. personnel were stationed. That attack left one American contractor dead and several Iraqi and U.S. troops wounded. The Iraqi parliament responded to the airstrike -- which took place near Baghdad International Airport -- by approving a resolution to end an agreement that would have allowed the U.S. to keep troops in the country to continue the fight against ISIS.
