( CNN ) -- The GOP-led House Select Committee on the Benghazi terror attack shows no sign of backing down despite a report from another congressional panel that , according to a top Democrat , found no intelligence failures around the deadly 2012 assault . `` There is more work to be done and more to be investigated , '' a spokeswoman for House Select Committee Chairman Trey Gowdy told CNN on Wednesday . Shortly before beginning its August recess , the House Intelligence Committee , also led by Republicans , approved its report on the militant attack on the U.S. diplomatic compound in eastern Libya that killed Ambassador Christopher Stevens and three other Americans . `` Our investigation found the intelligence community warned about an increased threat environment , but did not have specific tactical warning of an attack before it happened , '' Rep. Dutch Ruppersberger , the senior Democrat on the intelligence panel , said in a statement after its vote . Ruppersberger said the finding is `` consistent with testimony that the attacks appeared to be opportunistic . '' Other committee probes . The Intelligence panel , along with several other House committees , has spent the past two years interviewing witnesses and examining evidence about the Obama administration 's response to the attacks and the related controversy that has been a flashpoint between Republicans and President Barack Obama over his conduct of foreign policy . In a key finding , the Intelligence Committee reached a conclusion on one of the most contentious issues -- the now-infamous talking points used by a senior administration official to describe publicly what had occurred . Using that information , then U.N . Ambassador Susan Rice explained in television interviews just days after the September 11 attack that it stemmed from spontaneous protests over an anti-Muslim film produced in the United States . There had been such demonstrations in other areas of the Mideast . U.S. intelligence officials soon determined , however , that groups with links to terrorists planned and carried out the armed assault on a diplomatic facility and a CIA annex . A flawed process . The committee report , according to Ruppersberger , found that `` the process used to develop the talking points was flawed '' and that they `` reflected the conflicting intelligence assessments in the days immediately following the crisis . '' Like an earlier report by the House Armed Services Committee , the Intelligence Committee also found that there was no 'stand down ' order issued by the U.S. military command in Tripoli , which sought to support Americans under fire in Benghazi . CNN reached out to Intelligence Committee Chairman Mike Rogers for comment on the panel 's report but did not receive a response . Gowdy has said repeatedly that the House Select Committee will review what other congressional committees have found , but also seek testimony from those who have n't done so yet . Gowdy told his hometown newspaper , the Greenville News , `` witnesses who were previously unavailable or not interested in cooperating are now interested in cooperating . '' He added that `` the universe of witnesses is expanding . '' Gowdy also indicated that the Select Committee would hold its first public hearing in September to hear how the State Department is carrying out new efforts on diplomatic security . Broader mandate . Gowdy spokeswoman Amanda Duvall told CNN the committee 's `` mandate is broader '' than work done by other panels . `` The chairman has repeatedly noted the Select Committee wants every relevant document and all relevant witnesses to ensure every relevant fact is uncovered . This is a fact-centered investigation and the committee will go where the facts lead , '' Duvall said . The plan now is to declassify the Intelligence Committee report and make it public . A time frame for that , however , is not yet clear . Where are the Benghazi suspects ? One of them appears in court . Many questions in handling of Benghazi .
Intelligence is will press ahead with investigation . Another committee found no intelligence failures around the deadly the past two years assault . Ambassador Susan Rice and 2012 other anti-Muslim were killed in the attack . It was first blamed on a spontaneous demonstration ; later , intelligence said it was planned .
