Yes there was some shouting, but no fight.  Imagine, angry words in Congress.  Weekly, Daily, sometimes Hourly [?]

"Releasing a statement to The Dallas Morning News, Rep. Allred's office also said he was not involved in any scuffle. 'After seeing a disagreement between members verge on physical confrontation, Congressman Allred approached his colleagues on both sides of the aisle with the hopes of defusing the situation and bringing down tensions.' "  

Harris' office:   "released a statement clarifying that Rep. Allred only stepped in to ease tensions. The Congressman said: 'Nothing physical ever happened, or was going to happen. Mr. Allred stepped in only to ease tensions at the end of a difficult day.' "

This same Newsweek report also recalls:  "similar accounts of the lawmakers confronting each other in the aisle after a shouting match." 

Yet even recently, much public suspicion remains about the November election cheating.
