Just two days after Donald Trump won a presidential mandate in the US, former President Barack Obama warned him not to take Michael Flynn into his team. Even three of Obama's administration officials told NBC News that Obama had warned Trump during the last year's overview meeting that Flynn was not a good choice for a national security advisor.

Flynn's lies to Mike Pence

Trump did not listen and his administration found out just three months later that Flynn lied to Vice President Mike Pence about his contacts with the Russian ambassador to America.

Flynn is suspected because of several telephone conversations with the Russian ambassador in Washington before Trump's takeover of duties and the way he communicated with Vice President Mike Pence.

"The media is spreading the fake news that is raging with blind hate speech," Trump wrote on the social network at the time, pointing his finger towards the liberal television networks.

Independent writes that Flynn was the director of an intelligence agency during Obama's mandate, in the period from 2012 to 2014, and when he left as head of the agency, rumors were circulating that he was forced to do so because of the bad management of the agency.

Salley Yates to testify before the Senate

Former US State Attorney Sally Yates will testify before the Senate about warning President Trump of Michael Flynn's relationship with Russia.

This testimony will shed some light, according to CNN, about Trump's links with Russia. Especially if, as expected, Yates remains true to her statement that she warned Trump's leaders that Flynn, now a former national security advisor, was not telling the truth about his contacts with Russian ambassador to the United States, Sergey Kislyak.

It is expected that Yates will repeat before the Senate that the White House was given a "strong warning" about the relationship between Flynn and the Russian intelligence services. White House Officer Reince Priebus and Press Commissioner Sean Spicer agreed that Yates had forwarded the information which the White House checked.

President Donald Trump insisted on several occasions that the idea of his team members being connected with Russian intelligence services was "fake news". In the matter of Yates witnessing before the Senate, Donald Trump commented on Twitter.

"Ask Sally Yates, under oath, if she knows how the classified information got into the newspapers soon after she explained it to W.H. Council."
