The White House's anger about leaks is growing, and the Trump administration is stepping up efforts to crack down on them.

The attorney general and the national intelligence director are set Friday to discuss what the Justice Department calls 'leaks of classified material threatening national security.'

'No one is entitled to surreptitiously fight to advance battles in the media by revealing sensitive government information,' Attorney General Jeff Sessions said Friday.

'This culture of leaking must stop,' he added.

A presidential adviser is raising the possibility of lie detector tests for the small number of people in the West Wing and elsewhere with access to transcripts of President Donald Trump's phone calls.

The White House has become a hotbed of leaks, and the Justice Department is considering using lie detector tests in the West Wing

The Washington Post has published transcripts of his conversations with the leaders of Mexico and Australia.

Trump counselor Kellyanne Conway told 'Fox & Friends' on Friday morning that 'the West Wing is a small place. Each of these agencies is relatively small. It's easier to figure out who's leaking than the leakers may realize.'

'But on this matter I want there to be bipartisan outrage because we need people to understand this imperils national security.'

And might lie detectors be used? She said: 'Well, they may, they may not.'

'What really should concern everyone,' Conway added, 'are these leaks that imperil national security. Leaking the phone calls between our president and other heads of state is nothing short of a national disgrace.

'And you know who agrees with that? Democratic senator from Virginia Mark Warner. He said so yesterday. He said governors, senators and indeed presidents of the United States need to have confidence that they can engage in conversations with other heads of state.'

Sessions and his deputy, Rod Rosenstein, are holding a news conference at the Justice Department. They'll be joined Dan Coats, the director of national intelligence, and William Evanina, the government's top counterintelligence executive.

Trump complained on Twitter last week that Sessions was 'weak' when it comes to cracking down on leaks of classified information.
