The effort to take aim at Justice Department (DOJ) officials could put Republican leaders in a tough spot, especially as they seek to protect vulnerable House members in the midterms.

“We now live in a time when the administration appears to be actively coordinating with members of the majority to stymie Congressional and DOJ investigations,” Rep. Jerrold Nadler (D-N.Y.), the ranking member on the House Judiciary Committee, said in a statement. “We need to do everything in our power to protect the integrity and independence of the Department of Justice.”

Ryan, who is retiring, has said in the past that Mueller’s job is not in jeopardy and that the special counsel should be allowed to carry out its mission.

“I think they should be allowed to do their jobs,” Ryan told reporters at a news conference last week, referring to Mueller and Rosenstein.

On the one hand, Congress taking aim at Rosenstein would throw some red meat to the conservative base and please critics of the department’s Russia investigation. That could help close an expected enthusiasm gap between Republicans and Democrats in the midterm elections.

But moderate and vulnerable GOP lawmakers may be wary to take any action that could be construed as an attempt to undermine the special counsel.

Leaders of the far-right House Freedom Caucus have been blanketing the cable airwaves in recent weeks with their attacks on the Justice Department and FBI, which they claim have been biased and politically motivated in the investigation into Russian interference in the 2016 election.

They are infuriated that the Justice Department has slow-walked a request from Congress to produce a tranche of documents that touch on a range of issues, including the investigation surrounding former Secretary of State Hillary Clinton Hillary Diane Rodham ClintonButtigieg stands in as Pence for Harris's debate practice Senate GOP sees early Supreme Court vote as political booster shot Poll: 51 percent of voters want to abolish the electoral college MORE’s private email server and how the department has used the Foreign Intelligence Surveillance Act.

Judiciary Chairman Bob Goodlatte (R-Va.) slapped a subpoena on the Justice Department to force officials to turn over 1.2 million pages of documents by April 5.

But the department failed to comply with that deadline, and has so far only turned over a few thousand documents, some of which have been heavily redacted.

The department has since taken steps to help speed up its response to the congressional request, including appointing a United States attorney to help produce more documents.

If the DOJ doesn’t move more quickly or continues to hand over heavily redacted documents, Rosenstein could face impeachment proceedings or attempts to hold him in contempt of Congress, Meadows and others warn.

“Rod Rosenstein’s real problem right now is more with Congress than the president,” said Meadows, who ticked off a list of grievances. “He needs to get serious about responding to congressional requests in days, not in weeks or months.”

Either motion would require the support of GOP leaders, who decide what comes to the House floor.

It’s unclear, however, whether there’s much appetite in the wider GOP conference for targeting Justice officials — especially as speculation swirls about whether Trump will shake up DOJ leadership after the FBI’s raid on his personal lawyer earlier this month, which Rosenstein reportedly signed off on.

Some Republicans fear that the firing of Mueller, Rosenstein or Attorney General Jeff Sessions would cause chaos in Washington, spark a constitutional crisis and dim Republican hopes of holding their congressional majorities.

Over half of Republicans, or 55 percent, believe that Trump should not fire Mueller, according to a Quinnipiac University poll conducted earlier this month. Meanwhile, 69 percent of independents and 82 percent of Democrats feel the same way.

In a sign that some Republicans may be worried how the issue will play out in November, two of the GOP’s most vulnerable members — Reps.

“I am a supporter of the Mueller investigation ... It's important that the Mueller [probe] continue,” Lance told CNN’s Don Lemon this week. “I hold town hall meetings regularly, and my constituents want to get to the bottom of how the Russians were involved in tampering with our elective process.”

But, Lance added, Rosenstein’s ouster wouldn’t necessarily spell doom for the special counsel.

“The Mueller investigation would continue, and if someone were to be nominated to be deputy attorney general, that position requires Senate confirmation,” he said.
