WASHINGTON — More Republicans are telling President Donald Trump in ever blunter terms to lay off the criticism of special counsel Robert Mueller and the Russia probe. But party leaders are taking no action to protect Mueller, embracing a familiar strategy with the president — simply waiting out the storm.

Trump blistered Mueller and his investigation all weekend on Twitter and started in again Monday, questioning the probe’s legitimacy with language no recent president has used for a federal inquiry.

Mueller is leading a criminal probe into whether Trump’s 2016 presidential campaign had ties to Russia and whether there has been obstruction of justice since then.

Trump was told to cut it out on Sunday by such notable Republicans as Trey Gowdy, chairman of the House Oversight Committee, and Bob Corker, chairman of the Senate Foreign Relations Committee. Then on Monday he was told that firing Mueller would be “the stupidest thing the president could do” by Orrin Hatch, chairman of the Senate Finance Committee.

But Hatch, on CNN, also said he didn’t see any need for legislation to protect Mueller. And that sentiment was echoed by GOP leaders.

In recent months, bills to protect the special counsel have stalled, and Republican leaders have stuck to muted statements endorsing Mueller or denying he is in trouble. So far, that tactic has worked for them as Trump has lambasted the Russia investigation on Twitter but allowed Mueller to continue his work.

Democrats say legislation is needed. But GOP leaders saw no reason to leap to stop a firing they don’t think is in sight.

“I don’t think that’s going to happen so I just think it’s not necessary, and obviously legislation requires a presidential signature,” said Texas Sen. John Cornyn, the No. 2 Republican in the Senate.
