Congressional Democrats prodded Republicans on Tuesday to be aggressive and even-handed as lawmakers prepared to launch investigations into U.S. intelligence assertions that Russia intruded into last month’s elections to help Donald Trump win the White House.

In a written statement, No. 2 House Democrat Steny Hoyer of Maryland and the top Democrats on six House committees said they wanted a congressional probe of Moscow’s interference “that is truly bipartisan, that is comprehensive, that will not be restricted by jurisdictional lines.”

The Democrats said the analyses should produce “a complete and full accounting of what happened consistent with safeguarding our national security.”

The statement seemed to suggest Democrats are wary that the planned investigations — by intelligence committees headed by GOP chairmen in both chambers — might not be as tough as needed.

Senate Majority Leader Mitch McConnell and House Speaker Paul Ryan said Monday they backed investigations by each chamber’s intelligence committee into the CIA’s finding that Russia had interfered with the election.

McConnell declined to say whether he agreed with the CIA assertion that Russian hacking and public release of Democrats’ emails during the presidential campaign were designed to aid Trump. But in a noteworthy departure from Trump’s rejection of that conclusion, McConnell said the Senate Intelligence Committee would study the issue.

“It’s an important subject, and we intend to review it on a bipartisan basis,” McConnell said.

Ryan endorsed an ongoing investigation by the House Intelligence Committee into cyberthreats from other countries and extremist groups and condemned “any state-sponsored cyberattacks on our democratic process.” He said that examination would continue, with his support.

“Any intervention by Russia is especially problematic because under President (Vladimir) Putin, Russia has been an aggressor that consistently undermines American interests,” Ryan said in a written statement.

The remarks by McConnell and Ryan contrasted with Trump’s oft-repeated praise of Putin and dismissal of the CIA’s findings. Trump on Sunday called the CIA’s contention “ridiculous” and blamed the disclosures of the agency’s assessment on Democrats who he said were embarrassed over losing last month’s election.

McConnell said he has “the highest confidence” in U.S. intelligence agencies. He recounted Russia’s annexation of Crimea from Ukraine in 2014, said Baltic nation leaders are nervous about Moscow and pointedly praised NATO, which Trump criticized repeatedly during his campaign.

“I think we ought to approach all of these issues on the assumption that the Russians do not wish us well,” McConnell said.

Besides embracing an investigation by the Senate’s intelligence panel, led by Richard Burr, R-N.C., McConnell also expressed support for a related probe by the Armed Services Committee, chaired by Sen. John McCain, R-Ariz. McCain has been calling for such an examination and has long been wary of Russia.

The chairman of the House Intelligence Committee, Rep. Devin Nunes, R-Calif., released a letter Monday to National Intelligence Director James Clapper complaining that recent reports of the CIA’s conclusion clashed with Clapper’s prior statement to the panel that he lacked “good insight” about the connection between Russian hacking of Democratic campaign documents and their release by Wikileaks. Nunes requested a briefing on the subject for this week.

The GOP leaders expressed their views after a weekend in which Trump also said he would not need daily intelligence briefings, a staple of presidents’ days for decades and a flouting of a convention common for presidential transitions.

John Podesta , the campaign chairman for defeated Democratic presidential candidate Hillary Clinton, urged the Obama administration Monday to reveal what it knows about any Russian efforts to help Trump win. Podesta, whose emails were stolen and posted online, said the administration “owes it to the American people” to release details of the intrusions, which included the hacking of Democratic Party files.

Podesta said the Clinton campaign also supports a call by 10 of the 538 members of the Electoral College for Clapper to provide information that intelligence agencies have gathered on the subject.
