Your point being? The use of 'Nothing burger' has been around since the mid 1950s and it is not something that because a Trump family member starts using it, they're immediately associated with creating the word and who ever uses it agrees with them. [0]

This is the problem with erroneous guilt by associations just because someone you may not like used the phrase.
