President Donald Trump is mulling a number of strategy changes in the White House, The Wall Street Journal reported, citing several senior administration officials and outside advisers.

One possible outcome is incorporating a team of lawyers to vet Trump's tweets. One of his advisers said the aim is to set up a system so that tweets "don't go from the president's mind out to the universe."

The president is also planning to overhaul his top staff as well as hire outside lawyers to help manage the Russia probe, officials and allies told the paper. In addition, Trump may tap his former campaign officials Corey Lewandowski and David Bossie to help his administration deal with the investigation, and he may bring in David Urban for a senior White House role.

In addition, Communications Director Mike Dubke reportedly faces a threat to his job, and the administration may see Sarah Sanders taking over as the White House press secretary from Sean Spicer, the WSJ reported.
