State Department employees harboring anger about President Donald Trump's travel ban are welcome to find a new place to work, the White House said Monday.

The 100 signatories of a dissent memo that's circulating at State 'should either get with the program or they can go,' White House Press Secretary Sean Spicer declared.

'At some point if they have a big problem with the policies that he's instituting to keep the country safe, then that's up to them to question whether or not they want to stay or not,' Spicer told reporters during his daily briefing.

The cable, posted to web by the blog Lawfare, argues that Trump's executive order barring the State Department from issuing visas to citizens of Sudan, Iran, Yemen, Iraq, Syria and Libya will not achieve its stated purpose, to protect the country from terrorism.

It further points out that countries such as Pakistan and Saudi Arabia are not included in the order, even though citizens of those countries have committed acts of terrorism in the United States in the past.

The executive action will 'immediately' sour relations with the countries affected and 'much of the Muslim world, which sees the ban as religiously motivated,' the dissenters write.

'It will increase anti-American sentiment,' the draft memo argues, 'hostility towards the United States will grow.'

The State Department has confirmed the existence of the dissent cable, snippets of which appeared today in the Wall Street Journal.

'This is an important process that the acting secretary, and the department as a whole, respect and value,' State Department spokesman Mark Toner said, according to the NYT. 'It allows State employees to express divergent policy views candidly and privately to senior leadership.'

Dissent cables like the one that's making the rounds now are typically presented to the secretary of state. Trump's nominee, Rex Tillerson, has not yet been confirmed Senate.

Barack Obama's policy toward Syria was the source of consternation among career foreign service officers was last summer.

A group of 51 diplomats working in Washington and serving overseas urged the administration to intervene in the humanitarian crisis in Syria with military action.

Kerry graciously called the memo that was sent to his desk 'an important statement.'

'I respect the process, very, very much. I will . . . have a chance to meet with people when I get back,' he said during a visit to Copenhagen.

Trump's White House took a more abrasive approach to dissenters of the immigration order the president signed Friday afternoon.

'The president has a very clear vision. He's been clear on it since the campaign. He's been clear on it since taking office, that he's going to put the safety of this country first,' Spicer said during his briefing. 'He's going to implement things that are in the best interest of protecting this country prospectively, not reactively.'

He brought up polling showing that more Americans agree with the travel ban, that prohibits Syrians from coming the country indefinitely, than not and proclaimed that 'the American people support what the president is doing.'

They are 'pleased that this president is taking the steps necessary to protect this country,' he said.

'If somebody has a problem with that agenda, then they should ques – then that does call into question whether or not they should continue in that post or not,' he said of State Department employees protesting the travel restrictions.

The White House on Friday asked four career State Department officials, including Patrick Kennedy, undersecretary for management, to quit who were appointees of the previous president, allowing them to submit their resignation, in line with protocol.

Toner, a hold-over from the Obama administration himself, said the political appointees were in 'limited term positions.'

News reports initially said that diplomats were quitting in protest of Trump, but a State Department official told CNN those reports were wrong.

'These people are loyal to the secretary, the President and to the State Department. There is just not any attempt here to dis the President. People are not quitting and running away in disgust. This is the White House cleaning house.'
