An anonymous reader shares an article: Some Twitter users say President Trump should not be able to block them on the social network. The president makes unprecedented use of Twitter, having posted more than 24,000 times on his @realDonaldTrump account to 31.7 million followers. His tweets about domestic and foreign policy -- and media coverage of him and his administration -- has transformed Twitter into a public forum with free speech protections. That's the opinion of two Twitter users, who have the backing of the Knight First Amendment Institute. They are sending a letter today to the White House asking Trump to unblock them on his @realDonaldTrump Twitter account. Both users say they were blocked recently after tweeting messages critical of the President. Holly O'Reilly (@AynRandPaulRyan), whose Twitter account identifies her as a March for Truth organizer, said she was blocked on May 23 after posting a GIF of Pope Francis looking and frowning at Trump captioned "this is pretty much how the whole world sees you." In the letter to Trump and the White House, the Knight First Amendment Institute's attorneys argue that Trump's Twitter account "operates as a 'designated public forum' for First Amendment purposes, and accordingly the viewpoint-based blocking of our clients is unconstitutional." In some other news, Press Secretary Sean Spicer said today "@realDonaldTrump's tweets are official White House statements."
