We all know what happened, right?
Trump just assumed he could commandeer the Four Seasons hotel, tweeted without checking... then was notified that, no, he cannot have that venue- so he googled "four seasons Philadelphia" and picked the landscaping company, deleted the tweet and announced he meant four seasons landscaping the whole time...
And he believes he saved himself some embarrassment by doing that...
Because he avoided having it come out that a hotel told him no...
