Washington (CNN) Attorney General Jeff Sessions defended Rod Rosenstein on Thursday, saying he has "the highest confidence" in him one day after House conservatives introduced a resolution to impeach the deputy attorney general overseeing the special counsel Russia investigation.

"My deputy Rod Rosenstein is highly capable. I have the highest confidence in him," Sessions said during a news conference in Boston when asked about the impeachment effort against Rosenstein.

On Wednesday, GOP Reps. Mark Meadows and Jim Jordan took aim at Rosenstein by introducing a resolution to impeach. The move escalates an ongoing feud some House Republicans have had with the Justice Department, which they have accused of withholding key information from Congress.

The resolution on its own does not mean that the House is on the verge of voting to impeach the deputy attorney general, and conservative House members agreed Thursday morning to holding off on a vote to impeach Rosenstein until after the August recess.

Sessions suggested on Thursday that Congress should focus on other issues instead of targeting his deputy.
