Sen. Mark WarnerMark Robert WarnerGun control debate shifts to hardening schools after Texas shooting Warner: Why doesn't Trump understand that it's illegal for other countries to interfere in US elections? Warner sees 'credible components' in report that foreign governments offered to aid Trump campaign MORE (D-Va.) is an admitted fan of one particular quote ascribed to Winston Churchill. The only problem is, Churchill never actually said it.

As the quote goes — which other lawmakers often cite as well — Churchill once observed “Americans will always do the right thing, only after they have tried everything else.”

But as NPR reports, when Warner’s staff tried research the quote in order to mark their boss’s affinity for the saying on a plaque, they found squat.

WinstonChurchill.org’s Richard Langworth told the public radio syndicate, “I wish I could substantiate that [Churchill] said it. But so far, I cannot.”

Warner says when his staff told him about the Churchill quote snafu, he replied, “If Churchill didn’t say it, he should have.”

The senator acknowledged the common goof Monday on Twitter, writing of the phenomenon, "I am guilty of #ChurchillianDrift."
