GOP war on science?

The GOP tax bill makes grad students pay thousands of dollars a year in taxes on “income” they never receive so that the rich can pay less. I guess this is consistent with their anti-science stance. Trump canceled the White House Science Fair, appointed a radio talk show host as the Dept of Agriculture’s chief scientist and nobody as White House science adviser. Why would Ryan, McConnell, and Trump allow grad students to continue studying when they would just produce more science?
