Trump steps up fight over Russia probe, approves release of secret memo

The document, drawn up by congressional Republicans, alleges bias against Trump at the FBI and Justice Department in the investigations into Russian interference in the 2016 presidential election and ties between Moscow and the Trump campaign.

Ignoring FBI urgings, Trump approved the release of the memo, deepening an extraordinary showdown between the president and senior law enforcement officials over a probe that has dogged him for his first year in office and that is now headed by Special Counsel Robert Mueller.

As soon as Trump declassified the four-page memo, telling reporters its contents told a disgraceful story of bias against him, Republicans on the House of Representatives Intelligence Committee released it to the public.

The document alleges the FBI concealed the Democratic ties of a source the agency used to justify surveillance on a Trump campaign worker. It says a string of senior Justice Department officials signed off on this.

The memo has become a flashpoint in a battle between Republicans and Democrats over Mueller's criminal probe, which is also believed to be looking into any attempts to impede the investigation.

Democrats say Trump's allies hope to use the memo to protect the president and possibly to give him a reason to fire Deputy US Attorney General Rod Rosenstein, who hired Mueller and so would be the person to dismiss him, or even Mueller himself.

Asked by reporters on Friday if he had confidence in Rosenstein, Trump replied, "You figure that one out."

"A lot of people should be ashamed," Trump said of the findings in the document.

Trump has repeatedly complained about Mueller's investigation, denying any collusion or obstruction of justice. Moscow has denied any election meddling.

In a Twitter message on Friday, Trump accused top US law enforcement officers - some of whom he appointed himself - of politicising investigations.

It was his latest attack on top justice officials. Trump fired FBI Director James Comey in May last year. Comey later told a congressional hearing that he believed his removal was an effort by Trump to undermine the Russia probe.

Senator John McCain, who is regarded as a heavyweight in Congress on foreign affairs, strongly criticised his fellow Republicans and Trump for attacking the FBI and the Justice Department.

"Our nation’s elected officials, including the president, must stop looking at this investigation through the warped lens of politics and manufacturing partisan sideshows. If we continue to undermine our own rule of law, we are doing Putin’s job for him," McCain said in a statement, referring to Russian President Vladimir Putin.

Memo details

The document, commissioned by the Republican chairman of the House intelligence panel, Devin Nunes, uses the case of investigations into Trump campaign aide Carter Page, saying the FBI used a biased source to justify surveillance on him.

It alleges that a dossier of Trump-Russia contacts compiled by former British spy Christopher Steele, and funded in part by US Democrats, formed an “essential part” of requests to a special court to be allowed to conduct electronic surveillance on Page that began in October, 2016.

It says the initial application and subsequent renewal applications, signed off on by various senior Justice Department officials including Rosenstein, did not mention the link between Steele and the Democrats.

It also portrays Steele as biased, saying he “was passionate about him (Trump) not being president.”

The memo largely repeated allegations that Nunes and others had made publicly previously and did not appear to include major surprises.

Two days ago, in a rare public rebuke of the president and Republicans in Congress who were pushing to release the memo, the Federal Bureau of Investigation said it had "grave concerns about material omissions of fact" in the document and it should not be made public.

The FBI director, Christopher Wray, was appointed by Trump.

Democrats said the memo cherry picks information.

"The selective release and politicization of classified information sets a terrible precedent and will do long-term damage to the Intelligence Community and our law enforcement agencies," Democrats on the House intelligence panel said in a statement.

The Democrats said they hoped to release their own memo responding to the allegations on Feb. 5.

The entire file that the Justice Department used to apply for permission to eavesdrop on Page remains highly classified, making it hard to evaluate the memo’s contents.

In his swipe at US law enforcement leadership on Twitter on Friday, Trump said, "The top Leadership and Investigators of the FBI and the Justice Department have politicized the sacred investigative process in favor of Democrats and against Republicans - something which would have been unthinkable just a short time ago."

He praised "rank and file" FBI employees.

His latest salvo was sure to worsen the president's frayed relations with agencies that are supposed to be politically independent.

James Clapper, the former director of national intelligence under Democratic President Barack Obama, said Trump's attack on the FBI and Justice Department was the "pot calling the kettle black."

Seeking to defuse the conflict over the memo, Republican House Speaker Paul Ryan backed the release of a Democratic counterpoint document. His office said he backed making the Democrats' rebuttal public if it does not reveal intelligence gathering sources or methods.

Democrats say their counter-memo restores context and information left out of the Republican version. Republicans have resisted releasing that document.
