- The endorser must have an article or be unquestionably entitled to one
- This endorsement must be covered by reliable and independent sources
- Coverage of the endorsement needs to use the word endorse, or other closely related synonym.
This is covered by the consensus at WP:ERFC.
For that reason, Twitter, Facebook, Instagram, YouTube, poker websites, and blogs are not acceptable sources. Also, donating to a campaign or showing up to a campaign rally are not endorsements. Please let me know if you have any questions. Thank you - MrX 🖋 16:47, 10 January 2020 (UTC)
