Amid the celebrations of President Obama's victory, a Twitter tirade by Donald Trump is getting a lot of attention.
The moment it became obvious Obama had been re-elected, Trump tweeted: "This election is a total sham and a travesty. We are not a democracy. We can't let this happen. We should march on Washington and stop this."
NBC's Brian Williams didn't disguise his outrage on live TV.
Williams said, "Donald Trump, who has driven well past the last exit to relevance and veered into something closer to irresponsible is tweeting tonight."
Trump hit back today, tweeting Williams: "Wouldn't you love to have my ratings?"
Ed Klein, who wrote The Amateur, a controversial biography of the president, is also reacting. When INSIDE EDITION's Paul Boyd asked, "Do you still believe the evidence points to him being an amateur?"
Klein replied, "I've always thought he's an amateur as an executive. I've also always thought that he was a fantastic campaigner. There's a big distinction between running a campaign and governing. He does one very well, the other very poorly."
There were raucous celebrations across America, from New York's Times Square, to Los Angeles, where crowds followed the results on giant outdoor TV screens.
In Chicago, the wild celebrations of President Obama's victory contrasted sharply with the scenes at Romney headquarters in Boston where some of Governor Romney's supporters wept openly.
Americans everywhere vented their delight and disappointment with a record 31 million tweets
Former Saturday Night Live's Victoria Jackson tweeted: "I can't stop crying. America died."
Big-time Obama supporter Eva Longoria tweeted a photo of her election night party. And Beyonce posted an Instagram photo of herself in an Obama T-shirt.
Wall Street reacted too. The Dow started to tank right after the opening bell and dropped 300 points in morning trading.
Good wishes are pouring in to the president from around the world, including a note of congratulations from Prince William and Kate.
