(CNN)Oklahoma Republican Sen. James Lankford said Wednesday that he will intervene if the Trump administration has not allowed President-elect Joe Biden access to presidential daily intelligence briefings by the end of the week, one of the first rights of a presidential candidate after winning the election.

"There is no loss from him getting the briefings and to be able to do that," Lankford told radio station KRMG, noting that he sits on the Senate Oversight Committee and that he's already started engaging on this issue.

The Oklahoma Republican said if no progress is made on the issue by Friday, he will step in and say, "This needs to occur so that regardless of the outcome of the election, whichever way that it goes, people can be ready for that actual task."
