â€œItâ€™s not every day that a US President calls journalists â€˜among the most dishonest human beings on earthâ€™ or that his chief strategist dubs the media â€˜the opposition partyâ€™,â€ Steve Adler wrote.
â€œWe donâ€™t know yet how sharp the Trump administrationâ€™s attacks will be over time or to what extent those attacks will be accompanied by legal restrictions on our news-gathering.â€
Mr Adler said that although there had been debate over whether to oppose Mr Trumpâ€™s administration or boycott its press briefings, Reuters would continue the unbiased style of reporting it uses in countries â€œin which the media is unwelcome and frequently under attackâ€.
He cited examples asÂ Turkey, the Philippines, Egypt, Iraq, Yemen, Thailand, China, Zimbabwe and Russia, where journalists have been detained, killed, prosecuted, attacked, threatened, censored and denied visas.
â€œDonâ€™t take too dark a view of the reporting environment: Itâ€™s an opportunity for us to practice the skills weâ€™ve learned in much tougher places around the world,â€ the editor added.
Journalists are being advised to become â€œever more resourcefulâ€ and â€œworry less about official accessâ€, and not to be intimidated.
Reuters sources said the email had originally been sent internally to staff but was published in full after being leaked.
It came amid continued concern over Mr Trumpâ€™s treatment of the â€œmainstreamâ€ media, seeing him repeatedly target outlets including CNN and the New York Times, which have been critical of his policies.
His repeated use of the phrase â€œdishonest mediaâ€ has been compared to the Nazi-era term â€œLÃ¼genpresseâ€, meaning lying press, which has been used at right-wing events attended by the Republicanâ€™s supporters.
Mr Trump has spurned traditional methods of communication, delaying and cancelling press briefings following his election, and granted interviews with sympathetic minor outlets like the Christian Broadcasting Network over larger publications and networks.
Last week he accused the press of â€œdistortingâ€ his words to disparage him, saying he used his Twitter account to get his message across instead.
Mr Trumpâ€™s tweets have become notorious for his attacks on media outlets, which were repeating in speeches and onÂ the campaign trail, where he was lambasted for appearing to mock a disabled reporter last year.
The new US Presidentâ€™s style has earned unfavourable comparisons to hisÂ Turkish counterpart, who has seen dozens of journalists detained and newspapers closed in widespread purges since an attempted coup.
Recep Tayyip Erdogan praised Mr Trump for putting a CNN reporter â€œin his placeâ€ after he refused to take questions from the US broadcaster at a pre-inauguration press conference.
His pick for chief strategist was Steve Bannon, the chairman of self-declared â€œalt-rightâ€ website Breitbart, which is accused of propagating â€œfake newsâ€ with its vehemently anti-immigration agenda.
Meanwhile the new White House spokesman, Sean Spicer, has been ridiculed for holding up printed notes at official briefings and appearing to contradict the Presidentâ€™s own words on his controversial executive order temporarily banning refugees and visitors from seven Muslim-majority countries.
A group of United Nations rights experts warned that the policy â€œbreaches the countryâ€™s international human rights obligationsâ€ on Wednesday amid continuing protests and calls to impeach Mr Trump.Post published in: Featured
