How much is the government saving by using a facility that they already have evaluated for security?
A lot of people are making money on the G7 summit. I guarantee that previous summit locations are chosen by bribe. If Trump wasn't in the White House, nobody would blink an eye if his Florida property was chosen. This is just like the Scottland nonsense, which went away when it was revealed that the military used the same Trump property prior to him being President.
Being permanently offended by everything makes you a huge joke.
