Why is TAXPAYER money spent on the Obamas campaigning for Hillary?

[ColonelAngus]

Is her campaign refunding the American people for the cost of operating Air Force One and all the extra security detail necessary for the POTUS to campaign for Hillary?

 

[TNHarley]

I believe so. At least for air force one.

FACT CHECK: Air Force One, Who Pays?

 

[ColonelAngus]

"The rules allocate a portion of the flight costs to the DNC or the Clinton campaign. But they do not cover the full cost of operating Air Force One, estimated at $206,337 per hour."

Who supplements his pay when he is campaigning for Hillary?
