"This kind of thing cannot go unresponded to diplomatically", McCain, the head of the Senate Armed Services Committee, told MSNBC in an interview on May 18, adding that legal action could also be pursued.
Police said the fighting outside the Turkish ambassador's residence on Tuesday injured 11 people, including a Washington police officer, and led to two arrests for assault.
The meeting took place with a White House still responding to what a senior US official said was Trump's disclosure of classified information about an Islamic State terror threat involving laptop computers on aircraft. It said they chanted anti-Erdogan slogans, and that Erdogan's team moved in to disperse them because "police did not heed to Turkish demands to intervene".
The Turkish embassy did not respond to questions about why video evidence contradicts their statement or whether they believe violent attacks are an appropriate response to protests. "I'm scared now too because I don't know how it will affect my life here in the United States", said Tankan, who lives in Arlington, Virginia.
"All of the sudden they just ran towards us", said Yazidi Kurd demonstrator Lucy Usoyan.
The State Department confirmed that Turkish security personnel were involved in the altercation, which erupted after Erdogan met with President Trump at the White House.
Photos and videos posted on social media by witnesses showed a chaotic scene of flying fists, feet and police batons. "The case is now under investigation and we are not going to go into specifics or speculate on what may happen".
A video by Voice of America (VOA) released on Thursday shows that Turkish President Recep Tayyip Erdogan watched violent attack of his bodyguards and embassy staff to protesters outside of the ambassador's residence in the U.S. capital on Tuesday, Turkish Minute reported.
In September 2011, a brawl erupted between members of then Prime Minister Erdogan's security detail and United Nations security officers in the halls of the United Nations General Assembly in NY.
"This is the United States of America, this isn't Turkey, this isn't a third-world country, and this kind of thing can not go un-responded to diplomatically and maybe in other ways", McCain added.
The Turkish Embassy in Washington released a statement Wednesday that made no mention of any role played by the presidential guards but said that a group of Turkish American citizens who had gathered to greet Erdogan "responded in self-defense" to a "provocative demonstration".
The clash happened as President Recep Tayyip Erdogan returned to the embassy after meeting with President Donald Trump earlier Tuesday.
Investigators with the Metropolitan Police Department are working with the Secret Service and the State Department to identify the people on the videos. A group of Republican lawmakers called the incident an "affront to the United States" and called for Turkey to apologize.
The YPG says it is separate from the PKK, though Turkey does not accept this, and insists it does not want conflict with Ankara.
