After her previously scheduled appearance in front of the House Intelligence Committee was canceled by its Chairman, Devin Nunes, former acting Attorney General Sally Yates, is set to testify to Congress May 8. She will testify before the Congress about her meeting with the White House on Michael Flynn, reports said.

Yates is likely to recount her Jan. 26 conversation with White House Counsel Don McGahn when she said that she was worried about Michael Flynn's actual contacts with the Russian Ambassador Sergey Kislyak. Her testimony will contradict what the administration had stated publicly, a person familiar with that discussion and Yates' plans for testimony told the CNN.

White House officials have maintained that Yates merely wanted to give them a "heads-up" about Flynn's Russian contacts, however, she will reveal details about her alarming message to the White House about Flynn, which it ignored, the person said.

Yates will speak publicly for the first time about her meeting with the White House officials. However, according to the anonymous source, she will be limited as to what she can tell the Senate judiciary subcommittee as many details involving Flynn are classified in nature, report said.

Flynn was fired 18 days after Yates met McGahn, following news reports that Flynn had lied to Vice President Mike Pence about his conversations with Kislyak.

Yates was scheduled to appear in March before a House committee investigating Russian interference in the presidential election, but that hearing was canceled. At that time, Nunes canceled it, saying he wanted to hear in a classified setting from FBI Director, James Comey and National Security Agency Director, Mike Rogers.

The cancelation sparked hue and cry among the Democrats, who argued that Nunes was trying to protect the White House from controversial revelations about the Trump administration’s connections with Russia.

Trump had fired Yates in January, removing her as the nation’s top law enforcement officer after she refused to defend his executive order on travel ban that closed the nation’s borders to refugees and people from predominantly Muslim countries.

"The acting Attorney General, Sally Yates, has betrayed the Department of Justice by refusing to enforce a legal order designed to protect the citizens of the United States. This order was approved as to form and legality by the Department of Justice Office of Legal Counsel," the statement from the White House read.

Yates' appearance next week will throw light on the investigation on Trump administration and its Russian connection as it will be held after the investigations of FBI Director James Comey and National Security Agency Director Admiral Michael Rogers, which will take place this week.

The Senate judiciary subcommittee hearing will also see former National Security Advisor, Susan Rice testify before the committee next week, Sen. Lindsey Graham, the chairman of the panel, told CNN.
