After a high-stakes back and forth between the top Democrat and Republican on the House Intelligence Committee, Sen. John McCain said partisan bickering has cost Congress its credibility to investigate alleged Russian interference in last year's election, NBC News reported.
"I have not seen anything like it," McCain said Thursday on NBC's "Today" show about the infighting. "It is very disturbing."
McCain, R-Ariz., said it's up to House leadership to decide whether to change how the investigation is being conducted, and on Wednesday called for a congressional select committee or independent commission to take charge. Republican leaders on Capitol Hill have so far resisted such a move.
