President Donald Trump uses Twitter frequently to get his "unfiltered" messages out -- but he has recently decided who will not be receiving those messages.

Trump used his 140-character tweets throughout his 2016 campaign for the White House and continues to use the social media platform six months into his administration.

The president's account has blocked nearly 40 people from being able to view his tweets.
