The second source told CNN that "if the condition at the White House is elevated to RED and the President is moved" to the Emergency Operations Center "Melania Trump, Barron Trump and any other first family members would be moved as well."

Late Sunday night, the White House cautioned staffers who must go to work on Monday to hide their passes until they reach a Secret Service entry point and to hide them as they leave, according to an email which was viewed by CNN.

The email repeated mandates for maximum telework status and said there is still an "elevated security posture" due to the protests.

Trump praised the Secret Service the next day for its handling of the protests outside the White House Friday night in the wake of George Floyd's death last week in Minneapolis.

Healing, not hatred, justice, not chaos, are the mission at hand," Trump said.

Trump added that the voice of "law abiding citizens must be heard and heard very loudly."

"We must defend the rights of every citizen to live without violence, prejudice or fear," Trump said before supporting "the overwhelming majority of police officers who are incredible in every way and devoted public servants."

"No one is more upset than fellow law enforcement officers by the small handful who failed to abide by their oath to serve and protect," Trump added.

In his Saturday morning Twitter messages, Trump did not seek to lower the temperature or console Americans who find themselves facing parallel health and racial crises.

The decision to physically move the President came as protesters confronted Secret Service officers outside the White House for hours on Friday -- shouting, throwing water bottles and other objects at the line of officers, and attempting to break through the metal barriers.

At times, the crowd would remove the metal barriers and begin pushing up against the officers and their riot shields.

ET, Saturday morning.

The crowd thinned out and Secret Service officers were able to expand their perimeter and barriers around Lafayette Park across from the White House.

Six arrests were made during the protests, the Secret Service confirmed in a statement Saturday afternoon.

The President on Thursday had used the threat of police retaliation and military intervention in Minnesota where protests turned violent and destructive -- saying on Twitter that "when the looting starts, the shooting starts." Trump's weekend tweets also invoked imagery tied to brutal civil rights-era police tactics.

Now, a serious divide has emerged among the President's top allies and advisers over how the President should address several nights of protests and riots.

Trump is being urged by some advisers to formally address the nation and call for calm, while others have said he should condemn the rioting and looting more forcefully or risk losing middle-of-the-road voters in November, according to several sources familiar with the deliberations.
