washington correspondent oliver salat with his take on the allegations that prompted a formal impeachment inquiry 2 takeaways from today's testimony at number one president trump tried to ask the head of a foreign government for help in the 2020 election campaign number 2 staffers and aides of the white tells who are so concerned about the nature of they call that they essentially try to cover it up and that of course reminds of the mother investigation where special counsel robert muller followed allegations that trump and his team coated with the russians in the 2016 election campaign and that president trump later tried to shut down the investigations and this time around there is clear evidence for president trump's wrong doing and there might be more soon as america is waiting for yet another testimony of the whistleblower himself. iran's president hassan rouhani has called on the u.s. to end its policy known as maximum pressure he asked washington to return to quote dialogue logic and reason he went on to say his country is prepared to hold talks with the united states if president

remain out of public and even congressional view so earlier i asked our washington correspondent oliver salat what's left to find out. well we don't know for sure at this point what exactly was said in the 6 now famous phone call with the ukrainian president so the allegation is that president trump pressed the ukrainian president on the phone for dirt against joe biden but president tom tomorrow will publish the transcript of this phone call and he must be very certain that there are no there's no evidence inside the transcript but nancy pelosi made very clear that it's not about the wording of the phone call that it's implicit that she tried and that he in fact abuse power by freezing military funding that the ukraine is heavily dependent on for instance so and in addition to that we will have the whistleblower who initially leaked this information testified by the end of the week in the house intelligence committee where we do expect some damaging material most likely against the president we don't know exactly what he will say in the in that hearing 3 but we know we only get that informat

pleasure do you have you washington correspondent oliver salat says the presidential tweet has not in fact made trump's policy objectives any clearer. president trump's twitter threat is causing confusion the pentagon reportedly urging restraint and observers actually believed the firing of hawkish security adviser john bolton would pave the way for a more conciliatory tone president trumps tweet retching tensions with iran once again his plans of negotiating with iran's president rouhani are becoming more unrealistic while a new war is clearly not in the president's interest it also becomes obvious that the u.s. is lacking a strategy on the middle east and that puts both countries in a dangerous position that was our washington correspondent all over salat and now to some of the other stories making news around the world turkish president breccia air to one is preparing to host the leaders of russia and the rand for talks on syria acro wants to prevent any escalation of fighting in neighboring syria which could lead to more refugees entering turkey the e.u. is concerned that a new wa
