The Justice Department is reportedly blocking Senate investigators  from  speaking with FBI officials who may provide first-hand testimony  about  Donald Trump's firing of ex-FBI chief James Comey. It is the latest  sign that Special Counsel Robert Mueller could be  investigating the  sacking as part of his Russia-related probe.

The Justice Department, after weeks of tense negotiations, has agreed to provide Congress with key evidence collected by Robert S. Mueller III that could shed light on possible obstruction of justice and abuse of power by President Trump, the House Judiciary Committee said on Monday.

A watchdog organization has asked the Justice Department to investigate Treasury Secretary Steven Mnuchin for allegedly making repeated false statements to Congress about the conduct of OneWest Bank, where he served as CEO and later chair between 2009 and 2015. ”Mnuchin has repeatedly denied that his former bank engaged in robosigning foreclosure documents. The evidence is overwhelming that it did.

The House voted overwhelmingly and in bipartisan fashion to urge the Justice Department to publicly release the entirety of special counsel Robert S. Mueller III’s report into Russian interference in the 2016 election, once completed. The move is an attempt to “send a clear signal both to the American people and the Department of Justice” that lawmakers expect to see the full account of Mueller’s work, according to the House Judiciary Committee’s chairman, Rep. Jerrold Nadler (D-N.Y.).
