Retired Adm. William McRaven, the USA military leader credited with overseeing the 2011 raid that killed Osama bin Laden, wrote a scathing op-ed Thursday that chided President Trump for revoking the national security credentials of former CIA Director John Brennan.
In an open letter to Trump in The Washington Post, retired Admiral William McRaven wrote he would consider it an "honor".
"Through your actions, you have embarrassed us in the eyes of our children, humiliated us on the world stage and, worst of all, divided us as a nation", McRaven said of Trump.
Mueller has indicted or secured guilty pleas from 32 people and three companies, including Russian intelligence officials and former Trump aides.
US President Donald Trump says that although he has never obstructed justice in the Russian Federation investigation, he does "fight back".
"Mr. Brennan's lying and recent conduct characterized by increasingly frenzied commentary is wholly inconsistent with access to the nations' most closely held secrets", Trump said.
The president said he does not trust "many of those people on that list" and does not think they are "good people".
"The president has a constitutional responsibility to protect classified information and who has access to it, and that's what he's doing is fulfilling that responsibility in this action", White House press secretary Sarah Sanders said.
Turkey to boycott U.S. products including iPhone, says Erdogan
Kalin called on the United States to respect legal process in Turkey in reference to the American pastor's continued detention. Mr Erdogan suggested Turkey would stop procuring US-made iPhones and buy Korean Samsung or Turkish-made Vestel devices instead.
Mr Brennan vowed to continue calling the president to account, adding: "If Mr Trump believes that this is going to lead me to just go away and be quiet, he is very badly mistaken".
The president's comments were a swift departure from the official explanation given by the White House earlier on Wednesday that cited the "the risks" posed by Brennan's alleged "erratic conduct and behavior". She also questioned Brennan's "objectivity and credibility".
The Republican senator also said Trump has "full authority" to revoke Brennan's security clearance.
"The only questions that remain are whether the collusion that took place constituted criminally liable conspiracy, whether obstruction of justice occurred to cover up any collusion or conspiracy, and how many members of "Trump Incorporated" attempted to defraud the government by laundering and concealing the movement of money into their pockets", Brennan wrote in an op-ed published in the New York Times.
In a statement, Mr Trump stated he was also considering whether to stop access to classified information for fired Federal Bureau of Investigation director James Comey, former National Security Agency director Michael Hayden, former intelligence director James Clapper and former attorney general Sally Yates.
Former CIA director John Brennan fires back at President Trump, says he refuses to be silenced; reaction and analysis from the "Special Report" All-Stars.
Brennan has been a familiar face on television news shows where he has made scathing attacks on the president.
Following the president's summit last month with Russia's Vladimir Putin, Mr Brennan - who headed the Central Intelligence Agency under Mr Obama - described Mr Trump's behaviour as "nothing short of treasonous".
The former CIA and national intelligence bosses called Mr Trump's move "an attempt to stifle free speech" in a joint statement on Thursday.
