Obama, not only does he have flags flown at half staff, but his progressive, left wing programs and policies are responsible for most of the events for which the flag is flown at half staff.
BTW, as we all know, Omar Mateen was a gay Muslim democrat terrorist murderer.
Since this nation is in deep trouble, why not have them at half staff and raise them to full staff only when we have good news to trumpet. With the Kenyan in office, that would be almost never.
