Seems like the biggest critics are Trump's far right fake news supporters who are leaving Trump over the strike against Syria. They have been unhappy over the demotion of Bannon for the "liberal democrat" Jared Kushner and they have exposed several other cabinet and staff who they say are democrats and supporters of Obama and Hillary (there are some Trump staff, including the generals McMaster and Mattis, who have liberal and Democratic connections). McMaster did not want Trump to say "radical Islam". Mattis conflicts with Trump over climate and just made a speech calling climate change a major national security issue. Some are echoing Rand Paul (R) who said this is a false flag thing with some other country dropping the Sarin and not Syria.
