Samantha Power, U.S. ambassador to the United Nations under President Barack Obama, plans to testify before the House Intelligence Committee, according to a report Monday.

CNN reports that Power's appearance before the committee could happen before the August recess, although a date has not been finalized.

The news of Power's planned testimony comes on the same day that reports revealed Susan Rice, Obama's former national security adviser, will no longer provide testimony before the House Intelligence Committee this Tuesday.

Rice's testimony was delayed until a later date, CNN and others reported.

"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," said David Pressman, an attorney representing Power, in a statement to the Washington Examiner. "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."

Republicans have been interested in interviewing Rice and Power ever since numerous news outlets reported that Rice sought the identities of people close to President Trump whose communications were captured after the election in surveillance of foreigners by U.S. spy agencies.

Some Republicans have alleged that Rice and the outgoing Obama administration unjustifiably unmasked, as the process of making identities known is called, and then leaked damaging conversations involving Trump's team.

The testimony of the former Obama administration officials would be a part of the House Intelligence Committee's investigation of Russia's election interference, and the potential that the Trump campaign worked with Moscow.
