US President Donald Trump has been warned by fellow Republicans against interfering in special counsel Robert Mueller’s investigations.
It came after he attacked Mr Mueller’s inquiry into Russian interference in the 2016 US presidential election.
In tweets at the weekend, Mr Trump reiterated that there had been “no collusion” between his team and Russia and called the probe a “witch hunt”.
He added that it was dominated by “hardened Democrats”.
Mr Mueller, a highly regarded former head of the FBI, is a Republican.
Republican Senator Lindsey Graham said Mr Mueller should be allowed to proceed without interference, and that many Republicans shared his view.
He also warned Mr Trump against any attempt to dismiss Mr Mueller.
“If he tried to do that, that would be the beginning of the end of his presidency, because we’re a rule of law nation,” Mr Graham said.
