Trump had been scheduled to tour the factory Thursday where he also planned to sign executive orders related to American manufacturing.
White House spokeswoman Stephanie Grisham confirmed Trump is not expected to go to Milwaukee on Thursday.

Trump’s decision to temporarily ban citizens of seven Muslim-majority countries from traveling to the US and suspend the admission of all refugees has sparked a wave of protests nationwide — protests which now appear to have torpedoed the rollout of an unrelated part of his policy agenda.
