Stephen Colbert investigated over 'homophobic' anti-Trump joke

US comedian Stephen Colbert is to be investigated by the Federal Communications Commission (FCC) over a joke about President Donald Trump.
The body's chairman Ajit Pai said it received several complaints about the monologue, which some viewers branded homophobic.
It concerned crude sexual references involving Mr Trump and his Russian counterpart, Vladimir Putin.
Mr Pai told radio host Rich Zeoli he had now had a chance to watch the controversial clip, which aired on Colbert's CBS programme The Late Show last Monday.
"We have received a number of complaints," Mr Pai said. "We'll follow the standard operating procedures, as we always do, and make sure we evaluate what the facts are and apply the law fairly and fully."
The FCC is a US government agency which regulates TV and radio broadcasters.
CBS could be fined if it decides that Colbert's joke was indecent.
The FCC definition includes remarks that appeal to "an average person's prurient interest" or that "depict or describe sexual conduct in a 'patently offensive' way; and, taken as a whole, lack serious literary, artistic, political or scientific value".
Despite demands for him to be fired over the alleged slur, Colbert said on Wednesday that he would change "some of the words" in the monologue but did not regret it.
He then offered an olive branch to the LGBT community, saying: "Anyone who expresses their love for another person in their own way is, to me, an American hero."
One Trump supporter who took part in the movement #GaysForTrump, tweeted on Wednesday that Colbert's original rant was "homophobic" and "disgusting", while others repeated calls for his sacking.
A Twitter account devoted to getting Colbert sacked was set up on 3 May under the handle @firecolbert.
Many defended the comedian, however.

French election: Hollande vows 'response' to Macron hack attack

French President François Hollande has promised to "respond" after a hacking attack targeted presidential candidate Emmanuel Macron.
He gave no further details but said he knew of the risks of such attacks because they had "happened elsewhere".
The French media and public have been warned that spreading details of the attack would breach strict election rules and could bring criminal charges.
The centrist Mr Macron faces far-right candidate Marine Le Pen on Sunday.
A trove of documents - said to mix genuine files with fake ones - was released online shortly before campaigning ended on Friday.
Mr Hollande told Agence France-Presse on a visit to a cultural centre in Paris: "We knew that there were these risks during the presidential campaign because it happened elsewhere. Nothing will go without a response."
He did not elaborate, but Mr Macron's team has already been the victim of attacks which it blames on groups based in Russia and Ukraine, and last year's US election campaign was also the subject of hacking attacks targeting the Democratic Party.

Mr Hollande added that he could not say whether the attack was an attempt to destabilise the election.
The BBC's Hugh Schofield in Paris says the impact of the hacking attack on the vote is unlikely to be significant, as Mr Macron enjoyed a wide lead in opinion polls that were taken before campaigning ended.

Why is there a ban on spreading the data?

It is part of the restrictions that came into force at midnight local time on Friday.
No campaigning or media coverage of it that could sway the election is allowed until polls close at 20:00 local time (18:00 GMT) on Sunday. Some overseas French territories have already begun voting.
The election commission warned it could be a criminal offence to republish the leaked data.
Politicians and media are forbidden from giving details of, or commenting on, the leak.

The election commission said in a statement on Saturday: "On the eve of the most important election for our institutions, the commission calls on everyone present on internet sites and social networks, primarily the media, but also all citizens, to show responsibility and not to pass on this content, so as not to distort the sincerity of the ballot."

Can a ban work?

Analysts say that, given the open flow of social media content, policing this could be impossible.
The French daily Liberation covered the leak by publishing a general Q&A with a journalist.
Le Monde said it would "not publish the contents before the second round". It said it would vet and publish relevant material but "respecting our journalistic and ethical rules". It also carried a general Q&A of the leaks.
Florian Philippot, deputy leader of Ms Le Pen's National Front party, got a tweet in before the rules came in, saying: "Will Macronleaks teach us something that investigative journalism has deliberately kept silent?"

What data was released?

The documents were leaked on a file sharing website late on Friday. About nine gigabytes of data were posted by an anonymous user.
Mr Macron's En Marche movement said internal campaign documents, including emails and financial data, had been taken in an "act of massive, co-ordinated hacking".
"The leaked files were obtained several weeks ago by hacking personal and professional email accounts of several officials of the movement," it said in a statement.

How did the leaks spread?

The hashtag #MacronLeaks appeared on Twitter on an account used by a US alt-right figure on Friday afternoon - and was reportedly retweeted 87 times in the first five minutes, suggesting the use of automated bots to spread the information faster.
Within 90 minutes, the information had caught the attention of prominent supporters of Marine Le Pen and was further spread by bots.
Some three-and-a-half hours after the initial tweet, #MacronLeaks had been used some 47,000 times and the prominent Wikileaks account played a key role in publicising the hashtag.

Who might be responsible?

Unclear. The Macron camp has not blamed any specific party but said the hack clearly aimed to damage it and undermine French democracy,
It compared it to the leak of Democratic Party emails in last year's US presidential election that was blamed on Russian hackers.
Wikileaks, which published those emails, posted a link to the Macron documents on Twitter but implied it was not responsible.

Is this unprecedented?

Macron campaign servers went down for several minutes in February after attacks apparently originating in Ukraine.
And last month, security experts from the company Trend Micro said that Russian hackers were targeting Mr Macron's campaign, using phishing emails, malware and fake net domains in an attempt to grab login names, passwords and other credentials of campaign staff
Mr Macron's team said it suspected the Kremlin of wanting to help Ms Le Pen, who supports a pro-Moscow foreign policy.
Russia has denied that it is behind attacks aimed at Mr Macron.

What is at stake on Sunday?

France's voters have rejected the two big political parties - the Socialists and the Republicans - that have governed for decades.
Voters will be making a decision on France's future direction and on its place at the heart of the European Union.

Media captionHow Marine Le Pen's past has shaped who she is today
If they opt for liberal Emmanuel Macron, they will be backing a candidate who seeks EU reform as well as deeper European integration, in the form of a eurozone budget and eurozone finance ministers.
If instead they choose far-right Marine Le Pen she promises quite the opposite. She wants a Europe of nations to replace the EU.

What are the battleground issues?

One of the overriding issues is unemployment, which stands at almost 10% and is the eighth highest among the 28 EU member states. One in four under-25s is unemployed.
The French economy has made a slow recovery from the 2008 financial crisis and all the leading candidates say deep changes are needed.
Marine Le Pen wants the pension age cut to 60 and to "renationalise French debt", which she argues is largely held by foreigners.
Emmanuel Macron wants to cut 120,000 public-sector jobs, reduce public spending by €60bn (£50bn; $65bn), plough billions into investment and reduce unemployment to below 7%.
