WASHINGTON (AP) -- An Obama administration official who warned the Trump White House about contacts between one of its key advisers and Russia is set to speak publicly for the first time about the concerns she raised.
Former acting Attorney General Sally Yates is testifying Monday before a Senate Judiciary subcommittee investigating Russian interference in the 2016 presidential election.
The highly anticipated hearing it is Yates's first appearance on Capitol Hill since her firing in January is expected to fill in key details in the chain of events that led to the ouster of Michael Flynn, President Donald Trump's first national security adviser, in the early weeks of the administration.
The February resignation followed media reports that Flynn had discussed U.S.-imposed sanctions on Russia with Ambassador Sergey Kislyak during the presidential transition period, which was contrary to the public representations of the White House.
Yates is likely to testify Monday that she warned White House counsel Don McGahn on Jan. 26 that Flynn's contacts and the discrepancies between what the White House said happened on the calls and what actually occurred _ had left him in a compromised position, according to a person familiar with her expected statements. The person was not authorized to discuss the testimony by name and requested anonymity.
White House officials have said publicly that Yates merely wanted to give them a "heads-up'' about Flynn's Russian contacts, but Yates is likely to testify that she expressed alarm to the White House about the incidents, according to the person.
Trump has said he has no nefarious ties to Russia and isn't aware of any involvement by his aides in Moscow's interference in the election. He's dismissed FBI and congressional investigations into his campaign's possible ties to the election meddling as a "hoax'' driven by Democrats bitter over losing the White House. He's also accused Obama officials of illegally leaking classified information about Flynn's contacts with Kislyak.
Also scheduled to testify is former National Intelligence Director James Clapper, who attracted attention for a March television interview in which he said that he had seen no evidence of collusion between the Trump campaign and Russia at the time he left government in January. Republicans have seized on that statement as vindication for the Trump campaign, but investigations are ongoing.
The Associated Press meanwhile reported last week that one sign taken as a warning by Obama administration officials about Flynn's contacts with Kislyak was a request by a member of Trump's own transition team made to national security officials in the Obama White House for the classified CIA profile of Kislyak. The revelation came after interviews with a host of former U.S. officials, most of whom spoke on the condition of anonymity in order to discuss sensitive national security information.
Marshall Billingslea, a former Pentagon and NATO official, wanted the information for Flynn, his boss. Billingslea knew Flynn would be speaking to Kislyak, according to two former Obama administration officials, and seemed concerned Flynn did not fully understand he was dealing with a man rumored to have ties to Russian intelligence agencies. When reached by the AP last week, Billingslea refused to comment. Last month, Trump announced his intention to nominate Billingslea to serve as assistant secretary for terrorist financing at the Treasury Department.
Obama aides also described Flynn as notably dismissive of the threat Russia posed to the United States when discussing policy in transition meetings with outgoing national security adviser Susan Rice and other top officials.
Yates's warning about Flynn in January capped weeks of building concern among top Obama officials, the officials told the AP. President Barack Obama himself that month told one of his closest advisers that the FBI, which by then had been investigating Trump associates' possible ties to Russia for about six months, seemed particularly focused on Flynn.
Yates, a longtime federal prosecutor and Obama administration holdover, was fired Jan. 31 by Trump after refusing to defend the administration's travel ban. She had been scheduled to appear in March before the House intelligence committee, but that hearing was canceled.
The subcommittee meeting Monday is one of three congressional probes into the Russia interference, along with House and Senate intelligence panels. Yet questions remain about whether the Republican-led committees can conduct truly independent investigations.
Sen. Lindsey Graham, a South Carolina Republican and chair of the Senate Judiciary crime and terrorism subcommittee, has been outspoken about Russia's interference in the 2016 election and called for a stronger U.S. response than the sanctions currently levied.
Graham and top Democrat Sheldon Whitehouse of Rhode Island promised a bipartisan probe, but last week it was revealed that Graham independently invited Rice to testify, without Whitehouse's sign-on. Rice, a longtime target of Republicans, declined because her attorney said the invitation came late and without bipartisan consent.
