As the White House maintains its posture of blocking any and all congressional oversight requests, an attorney who represented the last president to face impeachment proceedings warned Democrats "to pick and choose these battles very carefully" or risk losing the public's support of their "legitimate oversight function."
"The un-redacted Mueller report, I don't think that's the right battle," Jane Sherburne, the former special counsel to President Bill Clinton, said on an episode of ABC News' "The Investigation." "What is redacted adds only incrementally, in a very small way, to the vast amount of information that is already quite damning in that report, so I wouldn't have picked that battle."

Jerry Nadler, D-N.Y., voted to hold Attorney General William Barr in contempt of Congress for refusing to turn over an un-redacted version of the special counsel Robert Mueller's 448-page report.
Last week on "The investigation," White House press secretary Sarah Sanders called Nadler's actions "nothing more than a big dog-and-pony show."

But Democrats risk taking their investigations into the president too far, Sherburne warned. Reflecting on her time defending Clinton, Sherburne described how aggressive Republican oversight "helped President Clinton in some ways," advising Democrats not to be "goaded" into impeachment, as House Speaker Nancy Pelosi said last week.

On ABC News' "This Week with George Stephanopoulos" Sunday, House Intelligence Committee Chairman Adam Schiff, D-Calif., said the White House's stonewalling of Democrats "does add weight to impeachment."
While "there's plenty [of evidence] for impeachment," Sherburne said, "I think it would backfire."
"I do worry about that," Sherburne added. "When [Democrats] are pretty consistently saying, 'You know, I don't think we're going to go down that road,' [Trump] throws down another gauntlet and he's making it almost impossible for them not to respond in some way."

"If they're really serious about stiffing Congress -- all of these document requests and subpoenas and requests for witnesses -- yeah, I think that's a constitutional crisis," Sherburne said.
In light of the perceived "constitutional crisis," Sherburne lamented the White House strategy of offering "blanket" denials to Democrats in search of witnesses, testimony or documents.
"Just saying 'no' and stonewalling Congress was not something that was in our lexicon," Sherburne said. "We understood that there was a legitimate oversight function that Congress had, and we tried to work things out."
