Holder proposes expanded talks on Fast and Furious From Terry Frieden and Deirdre Walsh, CNN June 18, 2012 -- Updated 1920 GMT (0320 HKT) Attorney General Eric Holder testified before the Senate Judiciary Co The attorney general and congressional leaders may meet Tuesday A House panel threatens to vote on a contempt measure against Holder At issue are documents the panel seeks on the Fast and Furious operation Washington (CNN) -- Attorney General Eric Holder agreed Monday to meet with the Republican chairman of the House Oversight Committee, but sought to add top congressional Democrats in the latest step of a showdown over the panel's push for more Department of Justice documents on the botched Fast and Furious gun-running sting operation. Rep. Darrell Issa of California, the chairman of the House committee, has scheduled a vote later this week on a measure citing Holder for contempt for failing to turn over the documents he seeks. However, Issa offered Friday to postpone the vote if Holder followed through on an earlier pledge to turn over some of the documents. Issa also agreed last week to a meeting on the issue, as requested earlier by Holder, but made clear he wanted the documents ahead of time and also wanted Sen. Charles Grassley of Iowa -- the ranking Republican on the Senate Judiciary Committee and a leading critic of Holder -- to take part. In a letter Monday responding to Issa, Holder agreed to a meeting on Tuesday. However, Holder said the meeting should also include the chairman of the Senate Judiciary Committee -- Pat Leahy of Vermont -- and the ranking Democrat on Issa's panel -- Rep. Elijah Cummings of Maryland. Holder also indicated he would turn over the documents at the meeting, rather than ahead of time. His letter said the purpose of the meeting would be to reach an agreement that would avoid a "constitutional confrontation" -- a reference to the committee's planned vote on the contempt measure. Justice officials and Issa's committee have been battling for months over the materials sought by the chairman, with Issa accusing the attorney general of stonewalling the investigation into Fast and Furious. Holder fended off a call for his resignation last week at a Senate Judiciary Committee hearing, where Sen. John Cornyn, R-Texas, accused him of misleading Congress over the Fast and Furious program and other misdeeds. CNN's Tom Cohen and Ted Barrett contributed to this report.
