Portland's mayor has called on federal officials to revoke the permit given to a alt-right rally scheduled to take place in his city this weekend.

A 'Trump Free Speech Rally' is planned for Sunday in Portland's Terry Schrunk Plaza, and if it goes ahead, it will be staged just eight days after a white supremacist allegedly stabbed two men to death and injured another on a MAX train in the city.

Jeremy Joseph Christian, 35, is accused of killing Rick Best, a Portland employee and retired Army platoon sergeant who served for 23 years, and 23-year-old Taliesin Myrddin Namkai-Meche, while seriously injuring Micah David-Cole Fletcher, 21.

The trio came to the defense of two teenage girls - one of whom was wearing a hijab - who were being racially abused by Christian.

Portland Mayor Ted Wheeler (pictured on Saturday, May 27) has called on federal officials to revoke the permit given to a alt-right rally scheduled to take place in his city this weekend

Mayor Ted Wheeler called on the event organizers to show respect for those who died and cancel the event, while also pressuring the federal agency to pull the permit.

'I have confirmed the City of Portland has not and will not issue any permits for the alt-right events scheduled on June 4th or June 10th' he said.

'The federal government controls permitting for Schrunk Plaza, and it's my understanding they have issued a permit for June 4th.

'I'm calling on the federal government to immediately revoke any permits they have issued for the June 4th event, and I am asking them not to issue a permit for the June 10th event.'

'I am appealing to the organizers of the alt-right events to cancel the events they have scheduled. I urge them to ask their supporters to stay away from Portland at this difficult time,' the mayor said on Monday

The event this Sunday is described as a pro-Trump rally, while the June 10 is a 'March Against Sharia'. They are both organized by the same person, Joey Gibson, who uses the name 'Patriot Prayer' on social media.

The mayor continued in his speech: 'Our city is in mourning, our community's anger is real, and the timing and subject of these events can only exacerbate an already difficult situation.

'I am appealing to the organizers of the alt-right events to cancel the events they have scheduled. I urge them to ask their supporters to stay away from Portland at this difficult time.

'On Friday, three men stood up against bigotry and hatred. Two paid with their lives, and a third is seriously injured.

'Our community remains in shock and mourning, but we are also tremendously grateful to our heroes and their families. They'll serve us for many generations to come to be loving, courageous people, and that's who we are meant to be.

'There is never a place for bigotry or hatred in our community, and especially not right now.'

The 'Trump Free Speech Rally Portland' is currently scheduled to go ahead on Sunday at 2pm in Schrunk Plaza

Taliesin Myrddin Namkai-Meche, 23, was stabbed to death on a Portland MAX train Friday after witnesses allegedly after confronting suspect Jeremy Joseph Christian, a white supremacist who witnesses say was directing hate speech at two young women

A Facebook page for the event, which at 9am on Tuesday listed 270 people were attending the rally, was flooded with mixed reactions to the mayor's call for respect.

'You have the right to exercise free speech. But if you wanted to show some dignity and true patriotism you'd cancel this event yourselves, out of respect for a grieving community,' Cathie Schau wrote.

'In the memory of the MAX heroes, don't come here and peddle more hatred, Norm Lopez said.

'To those thinking about attending this event, please consider donating money to the families of Jeremy Christian's victims,' Justin Speers commented.

'How about you promote love, instead of racism? Ever think that may be a better way to solve our problems?' Matt Brehm added.

However, supporters of the alt-right rally seemed determined to push ahead with their event.

The accused is also a white supremacist who was pictured giving Nazi salutes at a free speech rally in April with an American Revolutionary War flag tied like a cape around his shoulders

After the mayor asked for the event to be canceled, some went to the group's Facebook page and echoed the call

However, some of the attendees seemed determined to go ahead with the march, with one even making a joke about the deadly attack last Friday

'Will be there patriots! Does anybody know a good meeting spot to meet up with. (sic) All you patriots before the event?' Jen Vineyard wrote.

'I don't think the feds will pull their permitting. I can't wait! I wonder if someone will stab me if I take Max, tho...,' Amy Hill said, seeming to make a joke about last Friday's shocking attack.

'Can't wait! I'll be there,' Danielle VanLiew commented.

'We remember for months Trump Supporters were beaten just for showing support For Trump. We will never forget that young man chased down and beaten horribly just for wearing a red hat. We became afraid to rally on the streets. No the tables are turned on Antifa scum bags. Our Patriot Army led by Kyle Chapman has beaten Antifa numerous times. No longer do we fear showing our support for the President,' Glenn Boegle added.

It was reported in the wake of Friday's attack that Christian, the alleged killer, was seen at a 'free speech' on April 29 organized by the same group.

He had tried to carry in a baseball bat, but it was confiscated by police, and was later spotted wearing an American flag and chains around his neck.

He walked among fellow protesters holding American flags and signs that said 'Trump Makes America Great Again.'
