Reid confronts fellow Democrat over ethics allegations

The two engaged in an angry, in-your-face exchange Wednesday after Grayson interrupted Reid at a Congressional Progressive Caucus meeting to challenge the senator over his criticism and calls for Grayson to abandon his Senate bid.

Reid reminded Grayson that he is "under ethics investigation and appears to be running a Cayman Islands hedge fund from his congressional office in order to line his own pockets because these things are true, as established by 74 pages' worth of evidence from the Congressional Ethics Committee," Orthman said.

A congressional review panel said last month there is "substantial reason to believe" that Grayson violated federal law and broke House rules in a number of business and legal activities and in managing his congressional office.

The House Ethics Committee is investigating allegations centered on a hedge fund Grayson started when he was outside Congress and legal work done by others for which Grayson may have been paid while he was in office.

Grayson and Murphy are seeking their party's nomination for the open Senate seat currently held by Republican Marco Rubio, who waged an unsuccessful campaign for the presidency.
