Mr Trump said in an inteview he was "very disappointed" in Mr Sessions
US President Donald Trump has said he does not "have an attorney general" in his fiercest attack yet on Jeff Sessions.
In an interview with Hill.TV, Mr Trump renewed criticism of Mr Sessions' decision to step aside from the inquiry into alleged Russian interference in the 2016 election.
He also said he was unhappy with Mr Sessions' response to immigration.
The attorney general is yet to respond to Mr Trump's comments.
It is unusual for a sitting president to attack their attorney general and critics accuse Mr Trump of trying to meddle in the legal system.
After the president criticised Mr Sessions last month, two key Republican senators signalled that they would support Mr Trump if he were to fire Mr Sessions after the November mid-term elections.
However, other Republicans told Politico they thought this would be a bad move and said they were standing by the attorney general.
Mr Sessions has pushed back against previous criticism by Mr Trump. "While I am attorney general, the actions of the Department of Justice will not be improperly influenced by political considerations," he said in August.
"I demand the highest standards, and where they are not met, I take action."
Mr Sessions was an early supporter of Mr Trump's presidential campaign.
But he left the Russia investigation - which is reportedly looking into whether Mr Trump attempted to obstruct justice - in 2017, citing a potential conflict of interest, and handed control to his deputy, Rod Rosenstein.
The president insists there was no collusion between his campaign and the Russian government, and denies he has attempted to obstruct justice.
What has Mr Trump said this time?
"I don't have an attorney general. It's very sad," Mr Trump said during Tuesday's interview.
He added that he was "very disappointed" about Mr Sessions' decision to leave the investigation.
Asked whether he would consider firing Mr Sessions, the president responded: "We'll see what happens. A lot of people have asked me to do that.
