YouTube puts context label on GOP presidential debate video: YouTube imposed a fact-checking label on a video of the "(Full) Fourth GOP Primary Debate" posted on candidate Nikki Haley's channel. YouTube put a context label that linked to the Bipartisan Policy Center page titled "Mail Voting is Safe and Secure." The text of the note read "Mail ballots submitted by voters who meet eligibility and validity requirements are counted in every election. Before they are counted, election officials vigorously verify the validity of every mail ballot submission." It is unclear why YouTube placed this context label on a full, unedited video of the fourth Republican debate for the presidential nomination.
