Classified testimony expected this week from former national security advisor Susan Rice has reportedly been delayed, CNN reported Monday.

The delay comes as the House Intelligence Committee seeks to get former United Nations Ambassador Samantha Power Samantha Jane PowerSupport swells for renaming Edmund Pettus Bridge in Selma to honor John Lewis after his death 'Obamagate' backfires: Documents show Biden, Obama acted properly 'Unmaskings' may be common — and that's the problem MORE to appear as well.

CNN said Power has agreed to speak to the committee, an appearance that could happen before the August recess.

Power’s counsel, David Pressman, said she supports a bipartisan probe into Russia’s meddling in the United States election and that she is “looking forward” to offering any help in addressing the threat from Russia.

“Ambassador Power strongly supports any bipartisan effort to investigate and address Russia’s interference in our electoral process and she wanted to engage both the House and Senate Committees charged with investigating it,” Pressman said in a statement.

“Long before receiving an invitation to engage the Congressional committees, Ambassador Power stressed the importance of determining the full extent of this threat to our national security and learning lessons from what has happened. ... Ambassador Power is very much looking forward to providing any assistance and encouragement she can to bipartisan efforts aimed at addressing this serious threat to our nation’s security.”

Republican lawmakers want to determine if either Obama official “unmasked” the identities of President Trump’s associates that were redacted in intelligence reports.

Rice, according to the report, had been slated to testify on Tuesday.

Several congressional committees are investigating Russia's election interference, President Trump's firing of former FBI Director James Comey and any interference from the Justice Department in FBI investigations.

And potential surveillance of the Trump campaign has been in the spotlight since Trump claimed on Twitter, without evidence, that he "found out that Obama had my 'wires tapped' in Trump Tower just before the victory."
