Trump's supposed to give a speech today trashing the Clintons, but assume he'll shift most of the focus to Orlando. Already called for repeal of birthright citizenship and a Muslim ban. Given that one of the Boston bombers was a naturalized US citizen and that San Bernadino husband and the Orlando shooter were US citizens at birth, would not be terribly surprising if Trump calls for a multi-generation ban of citizenship for Muslim immigrants. His supporters would be all over that along with deporting US citizens. Trump never admits mistakes, he just stops talking about them (birthers, 9/11 celebrations) and he clammed up on birthright citizenship relatively quickly, but won't be able to resist more xenophobia, religious bigotry, and shaky constitutional pandering.
