Another day has brought another Twitter row to Donald Trump's White House.
The US President likes to share his views with his 42 million followers on all manner of subjects – from world diplomacy to TV shows.
:: For 11 minutes, Donald Trump's Twitter ceased to exist
Here's a look back at some of Mr Trump's more controversial tweets.
:: Kim Jong Un
In perhaps one of his strangest attempts at Twitter diplomacy to date, Mr Trump criticised North Korean leader Kim Jong Un for calling him old – by suggesting he was taking the moral high ground.
In the past, he has referred to him as "Little Rocket Man".
Why would Kim Jong-un insult me by calling me "old," when I would NEVER call him "short and fat?" Oh well, I try so hard to be his friend – and maybe someday that will happen!

:: Meryl Streep
During her Golden Globes speech, the Hollywood star accused the President of bullying behaviour. But Mr Trump said he was unimpressed with Streep, one of the most successful actresses of her generation.
Meryl Streep, one of the most over-rated actresses in Hollywood, doesn't know me but attacked last night at the Golden Globes. She is a…..

Hillary flunky who lost big. For the 100th time, I never "mocked" a disabled reporter (would never do that) but simply showed him…….

"groveling" when he totally changed a 16 year old story that he had written in order to make me look bad. Just more very dishonest media!

:: Arnold Schwarzenegger
Schwarzenegger replaced the President as host of the Celebrity Apprentice reality show, but then said he was leaving. Mr Trump was not a fan – just one incident of a long-running feud between the men.
Arnold Schwarzenegger isn't voluntarily leaving the Apprentice, he was fired by his bad (pathetic) ratings, not by me. Sad end to great show

:: Whoopi Goldberg
Goldberg, who presents US show The View, criticised Mr Trump on air for racially-charged comments he had made during his presidential campaign. He responded by sharing his opinions on daytime television scheduling.
:: Macy's
Mr Trump's attack on Macy's was prompted by the department store's decision to drop the Trump menswear brand from their stores – after a campaign-trail speech portraying Mexicans as murderers and rapists.
I hope the boycott of @Macys continues forever. So many people are cutting up their cards. Macy's stores suck and they are bad for U.S.A.

:: Hillary Clinton
In retweeting – and then deleting – a GIF of himself knocking what appears to be Hillary Clinton to the floor with a golf ball, Mr Trump raised serious questions over his attitudes toward violence against women.
He also routinely refers to his former presidential rival as Crooked Hillary.
:: Ted Cruz
Few things underpin the gravity of accusations of misconduct more than a Jim Carrey movie, and to really highlight the importance of his concerns Mr Trump photoshopped Ted Cruz's head onto a movie poster.
:: CNN
Observers were dumbfounded by a Tweet, adapted from a past appearance on WrestleMania, that appeared to show Mr Trump attacking the CNN logo in a sinister realisation of his "fake news" crusade.
:: Mika Brzezinski
Mr Trump has long harboured a grudge against the presenters of TV show Morning Joe. But his particularly gendered insult toward host Mika Brzesinski raised alarm bells even with some from his own party.
I heard poorly rated @Morning_Joe speaks badly of me (don't watch anymore). Then how come low I.Q. Crazy Mika, along with Psycho Joe, came..

…to Mar-a-Lago 3 nights in a row around New Year's Eve, and insisted on joining me. She was bleeding badly from a face-lift. I said no!

:: Hamilton
When the cast of the popular musical addressed Vice President Mike Pence, who was in the audience, he responded by saying he'd enjoyed the show. But the that didn't stop Mr Trump taking issue with the criticism online.
The cast and producers of Hamilton, which I hear is highly overrated, should immediately apologize to Mike Pence for their terrible behavior

:: Honorary mention
While not an attack on anybody, this was one of Mr Trump's most baffling tweets. It has since been deleted, but not before giving rise to endless speculation – and mockery – online.
