Recent edit to Philo Farnsworth
Hello, and welcome to Wikipedia. I noticed that you made a change to an article, Philo Farnsworth, but you didn't provide a reliable source. It's been removed for now, but if you'd like to include a citation and re-add it, please do so! If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Thank you!

Please do not add or change content, as you did at Plan Colombia, without citing a reliable source. Please review the guidelines at Citing sources and take this opportunity to add references to the article. ''Stop doing this. You cannot add a claim in front of reference if it not supported by that reference. And your claim that I have a political agenda in undoing your edit is a personal attack.
