Twitter users are sharing a very important message today. People are holding a #TwitterBlackout on the platform to stand in solidarity after Donald Trump became the 45th president of the United States.

The Republican candidate beat out Democratic presidential candidate Hillary Clinton and will take office January 2017. Tweeting his win, he called it ” a beautiful and important evening,” adding that “we will all come together as never before.” According to CNBC, the White House statement read, “Ensuring a smooth transition of power is one of the top priorities the President identified at the beginning of the year and a meeting with the President-elect is the next step.”

Twitter users, however, were evidently disappointed that Trump was elected, as seen through trends such as #NotMyPresident, #StillWithHer and #TwitterBlackout. Users called on others to make their profile and cover photos black to stand in unity. Take a look at some of the reactions below:
