White House communications director Michael Dubke has resigned

Kellyanne Conway, White House counselor, told The Associated Press that Dubke handed in his resignation before President Donald Trump left for his international trip earlier this month.

In an interview on Fox News on Tuesday, Conway said Dubke "made very clear that he would see through the president's international trip, and come to work every day and work hard even through that trip because there was much to do here back at the White House."

Dubke's resignation comes amid a broader reported White House shake-up of its communications strategy. That includes introducing more rallies across the country so that Trump can speak directly with voters.

"The conventional ways of communicating are not working for them," one adviser told The Washington Post. "They have to get the campaign brand back" and be able to communicate with an audience instead of having the report on it, the adviser added.

Trump may also take more questions from reporters when he's traveling and during photo ops with foreign leaders.

"He says things exactly the way he wants them to be said," one official told Axios.

Aides have also floated possible changes to the daily press briefing and a downsized role for press secretary Sean Spicer. Some have discussed the option of having Spicer take on a more discreet and behind-the-scenes role following a series of press briefings that were widely-panned.

If Spicer is demoted, he will likely be replaced by deputy press secretary Sarah Huckabee Sanders, who took over Spicer's role in a number of press briefings as revelations continued to emerge in the Trump-Russia story.

The White House is also reportedly considering building a "war room" tasked with managing continuing developments in the Russia controversy.

The primary goal of the operation will be to more aggressively fire back at fallout in the wake of Trump's abrupt firing of FBI director James Comey on May 9.

The proposed war room, Axios reported, will be filled with "experienced veterans from the campaign trail who recognize the gravity of the situation."

The White House could turn to figures like former Trump campaign manager Corey Lewandowski and former deputy campaign manager David Bossie, for help in the "war room," the Post noted. Lewandowski was fired last year after a series of campaign trail blunders, and Bossie is known for his 20-year-long investigation into Bill and Hillary Clinton. Trump met with Bossie and Lewandowski on Monday.

Axios reported on Tuesday that Trump may also recruit GOP lobbyist David Urban, who was critical to handing him an upset victory in Pennsylvania during the 2016 election.

"The bottom line is they need fresh legs; they need more legs," Barry Bennett, a Trump campaign political adviser, told the Post. "They're in full-scale war, and they're thinly staffed."
