An Arizona restaurant has been forced to close down after posting a pro-Trump Facebook status saying the business supported 'OUR president'.

Christopher Smith and Jay Warren, the owners of Cup it Up American Grill in Tucson came under heavy criticism after posting the statement on their social media page last week.

It said: 'We believe in and support 100% in the following: OUR President, Always Standing for the National Anthem, repealing Obama Care…'

It went on to praise God, the Bill of Rights, the US Armed Forces and drug screening for welfare recipients.

It then said that the business did not support 'those that DON'T respect our President, Armed Forces and First Responders, kneeling for the national anthem, Antifa, fake news, global warming and late night hosts getting political'.

The post finished with: 'If you like this post, please share it with 5 friends and we look forward to your next visit! If you disagree with this post, please share it with 100 friends and we won't be expecting you anytime soon!'

It led to a furious backlash with the restaurant receiving numerous 'angry phone calls' with staff also opting to quit.

According to Ron Sanchez, whose daughter worked at the eatery, some people even threatened to burn down the restaurant with the owners in it.

Speaking about the reaction to the post, which has since been deleted, he told the ABC15 news channel: 'It's a crazy world we're in.'

Last week the restaurant posted a statement on its door saying: 'We have made a decision to close our doors indefinitely as of today, Monday, October 9, 2017.

'The safety of our employees, and our families is of great concern and is our #1 priority at this time.

'We would also like to extend a special thanks to our Military and first responders. Thank you all and God Bless.'

Ericka Ayup, a regular customer of the restaurant,said: 'I respected their decision to speak up and be patriotic whether people agree or not.

'It wasn't smart for them to do what they did from a business aspect especially being down here in the University -- which is more liberal and young.'
