>> Are you investigating President Trump?>> Investigators from Special Counsel Robert Mueller's probe into possible collusion between Russia and the Trump campaign have been questioning witnesses about events at the 2016 Republican National Convention. That's according to two sources familiar with the Mueller investigation. Reuter's correspondent, Mark Hozenball has the story.
>> What we reported is that Mueller's investigators have interviewed witnesses about things that happened at the Republican National Convention in Cleveland. Including why platform language, related to possible arming of Ukraine so they could protect themselves against future Russian invasions, was just dropped. According to the person who proposed it at the direct request of Trump operatives who told her, personally, that they were asked by Donald Trump himself to drop this language.
>> Mueller's team has also been asking about a convention related event attended by both Russia's US Ambassador and Jeff Sessions. The first US Senator to support Trump, and now his Attorney General.>> Another witness told me that the prosecutors were interested in whether he was talking to the Russian ambassador there.
They're already looking at Sessions as to what he might have said to the Russian ambassador, if anything, when he encountered him at a meeting at the Mayflower Hotel earlier.>> Hozenball says Mueller's interest in what happened at the RNC is a clear indication that Trump campaign contacts and actions related to Russia remain central to the special counsel's investigation.
>> They've clearly established this and some of these interviews that Mueller did took place pretty recently, in the last three or four months, that Muller is still very actively looking at this.>>
