It follows claims from a whistle blower that mr trump put pressure on the president of ukraine, to investigate joe biden, the democratic frontrunner in the race for the white house. The subpoenas are already flying. Secretary of state mike pompeo has been ordered to hand over documents concerning contact with the Ukrainian Government by next friday. As the democratic controlled House Foreign AffairsCommittee Puts it, your failure or refusal to comply with the subpoena shall constitute evidence of obstruction of the houses impeachment inquiry. President trump has lashed out at the inquiry saying its a witch hunt. Our north america editorjon sopel has the very latest. There is support and defiance but also there is anger. In a twitter feuds like this morning he took aim at the Democratic House intelligence committee, the person who will play a key role in impeachment hearings. The Inspector General found that credible. Donald trump said he must resign and be investigated. Hes been doing this for two years, hes a sick man. And then the whistle blower who revealed details of the president s conversation with his ukrainian counterpart. Sounding more like the so called whistleblower isnt a whistleblower at all. But everything in the letter has been proved true, the core did take place, President Trump did ask his ukrainian counterpart to investigate his Democratic Party rivaljoe biden and the white house today confirmed the transcript of the call was moved to a more secure server. But when President Trump asks ukraine to investigate corruption, the democrats want to impeach him. But now the Trump Campaign is firing back. They lost the election and now they want to steal this one. Dont let them. Im donald trump and i approve this. But the speaker of the house is unmoved and she says she was left with no other choice but impeachment following all of this. This is about the National Security of our country, and the president of the United States being disloyal to his own oath of office, jeopardising our National Security and jeopardising the integrity of our elections. And the woman donald trump beat in 2016 has also made a rare intervention to pile in. He has turned american diplomacy into a cheap extortion racket. He has denigrated and lets be honest stabbed in the back of the Career Foreign Service officers who serve bravely and selflessly no matter the politics of the administration that they are working under. The white house line on the whistle blower is that its all second hand information and inaccurate, its anything but, so far everything he has said has turned out to be true. Republican lawmakers can say they dont really care and donald trump is free to do whatever he likes, much harder, though, to say there is nothing here. John sopel, bbc news, washington.

Here in the uk its been announced that the independent office for Police Conduct will assess whether the Prime MinisterBoris Johnson potentially committed the criminal offence of misconduct in Public Office during his time as mayor of london. The allegations are that borisjohnson maintained a friendship with the american businesswoman and former model Jennifer Accuri and, as a result of that friendship, allowed ms arcuri to participate in trade missions and receive sponsorship monies in circumstances when she and her companies could not have expected otherwise to receive those benefits. The Police Watchdog will now consider if it is necessary for the matter to be investigated. Downing street has released a statement saying everything was done with propriety and in the normal way. Our uk Affairs CorrespondentDaniel Sandford has more. The basis of the allegations is that while he was mayor of london, Boris Johnsons friend, Jennifer Accuri, received £11,500 in sponsorship for events organised by whatever companies which came from organisations linked with the mayor s office. And also went on three overseas trips with borisjohnson which, originally, shed been turned down for. Now, the Greater LondonAuthority Monitoring officer has been looking at these allegations this week and so have we, in fact, and noticed that people who went on the trips with Jennifer Accuri felt that she seemed a bit out of place, as her companies didnt seem as substantial as those of the other people that were on the trips, and certainly we know that borisjohnsons office intervene to make sure that she went on one of the trips and the Greater LondonAuthority Monitoring officer has now decided to call in the Police Watchdog, the iopc, to assess whether Boris Johnson, the Prime Minister, should be investigated for the criminal offence of misconduct ion Public Office. The iopc are involved because when he was mayor of london, borisjohnson was in charge of londons metropolitan police. Borisjohnson has vigorously denied these allegations, saying to the bbc last night that people are barking up the wrong tree. His office insists that hes always acted with propriety. And he says very proud of his time as mayor of london. Daniel sandford.
