"I thought General Mattis's words were true and honest and necessary and overdue", Murkowski told reporters at the US Capitol.
The president has been criticised by opposition Democrats and members of his own Republican party after peaceful anti-racism protesters were forcibly cleared so he could pose with a Bible in front of St John's Church, in Washington DC, on Monday.
Former Secretary of Defense General Jim Mattis speaks at an event in NY, N.Y. on September 9, 2019. "So I appreciate General Mattis's comments".
"Donald Trump is the first president in my lifetime who does not try to unite the American people - does not even pretend to try", Mattis wrote in a blistering statement posted online by The Atlantic.
"Because you have the right to have a Secretary of Defense whose views are better aligned with yours on these and other subjects, I believe it is right for me to step down from my position", he said in his resignation letter.
"Never did I dream that troops taking that same oath would be ordered under any circumstance to violate the Constitutional rights of their fellow citizens - much less to provide a weird photo op for the elected commander-in-chief, with military leadership standing alongside".
Police on horseback begin to approach demonstrators who had gathered to protest the death of George Floyd, on Monday near the White House. He said he didn't like Mattis' leadership style and is glad he's gone.

Minnesota's attorney general has warned he needs to move methodically if he wants to secure convictions. The violence is intensifying, including incidents of police officers being hit by cars.
Trump has repeatedly claimed to have fired Mattis. Trump was accompanied to the church by officers together with Mark Esper, the secretary of protection, and Gen Mark Milley, the chair of the joint chiefs of workers.
Investigators also believe that groups have been training some demonstrators on techniques to rush officers on the lines of the protests and giving tips on how to avoid being arrested, the official said. But he said, "I was not aware a photo op was happening".
As Trump held a press conference in the Rose Garden on Monday afternoon, he threatened to deploy the military to cities he said were besieged by violent protesters, saying the armed forces would "quickly solve the problem for them". He added, "We are not in one of those situations now".
The demonstrations have been overwhelmingly peaceful but pockets of violence have at times emerged, and Trump has chosen to use aggressive rhetoric in response, including a threat to deploy the military. "If needed, he will use it", McEnany said Wednesday.
On Monday Trump threatened to send active duty U.S. troops to stamp out civil unrest gripping several cities, against the wishes of state governors - alarming current and former military officials who fear dissent in the ranks and lasting damage to the USA military itself, one of America's most revered and well-funded institutions.
