WASHINGTON

Ratcheting up pressure on the Russia investigation, the White House announced that top FBI and Justice Department officials have agreed to meet with congressional leaders and “review” highly classified information the lawmakers have been seeking on the handling of the probe.

The agreement came after President Donald Trump made an extraordinary demand that the Justice Department investigate whether the FBI infiltrated his presidential campaign. It’s unclear exactly what the members will be allowed to review or if the Justice Department will be providing any documents to Congress.

White House press secretary Sarah Huckabee Sanders said Trump chief of staff John Kelly will broker the meeting between congressional leaders and the FBI, Justice Department and office of the Director of National Intelligence.

She said the officials will “review highly classified and other information they have requested,” but did not provide additional detail.

During a meeting Monday with Trump, Deputy Attorney General Rod Rosenstein and FBI Director Christopher Wray also reiterated an announcement late Sunday that the Justice Department’s inspector general will expand an existing investigation into the Russia probe by examining whether there was any improper politically motivated surveillance.

Rep. Devin Nunes, an ardent Trump supporter and head of the House Intelligence Committee, has been demanding information on an FBI source in the Russia investigation. And Trump has taken up the cause as the White House tries to combat the threat posed by special counsel Robert Mueller’s investigation into potential ties between Russia and the Trump campaign.

Today, a group of conservative House lawmakers planned to call for the appointment of a second special counsel to investigate whether misconduct took place in the FBI and the Justice Department.

Trump tweeted Sunday, “I hereby demand, and will do so officially tomorrow, that the Department of Justice look into whether or not the FBI/DOJ infiltrated or surveilled the Trump Campaign for Political Purposes — and if any such demands or requests were made by people within the Obama Administration!”

With the demand, Trump entered into the realm of applying presidential pressure on the Justice Department regarding an investigation into his own campaign — a move few of his predecessors have made.

“If anyone did infiltrate or surveil participants in a presidential campaign for inappropriate purposes, we need to know about it and take appropriate action,” Rosenstein said in a statement announcing the move.

Rep. Adam Schiff of California, the senior Democrat on the House Intelligence Committee, has called Trump’s claim of an embedded spy “nonsense.”

“His ‘demand’ DOJ investigate something they know to be untrue is an abuse of power, and an effort to distract from his growing legal problems,” Schiff tweeted. “Never mind that DOJ has warned that lives and alliances are at risk. He doesn’t care.”

Trump’s demand of the Justice Department alarmed many observers, who felt it not only violated presidential protocol but also could have a chilling effect on federal law enforcement or its use of informants.
