White House aide Sebastian Gorka on Tuesday said the term "lone wolf" was coined by the previous administration "to make Americans stupid."
During an interview on MSNBC, Gorka was asked how to deal with the "lone-wolf lunatics."
"There's no such thing as a lone wolf," Gorka said.
"That was a phrase invented by the last administration to make Americans stupid ... There has never been a serious attack or a serious plot that was unconnected from ISIS or al Qaeda," he continued.
"At least through the ideology and the TTPs, the tactics, the training, the techniques and the procedures that they supply through the internet."
Gorka said there is an "international global threat."
"What we have to do now is not only destroy organizations like ISIS, which we are doing, they will be annihilated, but also delegitimize the ideology," he said.
"So it will become as heinous and as rejected as fascism and Nazism is today."
The phrase lone wolf reportedly dates back centuries, according to The Wall Street Journal. It has been used in the past to refer to a "criminal not associated with a gang," according to the publication.
During his time in the White House, former President Obama warned of the threat of lone-wolf terrorist attacks.
Gorka also said during the interview it's important to call the threat what it is.
"You cannot solve a problem unless you're allowed to talk truthfully about it," he said.
"So we will call it radical Islamic terrorism, we will target the ideology and we will call them out for being evil and we will work with our Muslim partners."
