Lindsey Graham was warned early Sunday morning to follow the Senate's decorum rules after he accused Sen.

Graham said that the amendment gave a bad name.

The South Carolina senator was warned not to impugn the motives of a fellow senator.

Murphy told Graham and all senators not to impute to another senator any conduct or motive worthy or unbecoming of a senator.

The admonishment came after Graham slammed Hassan for proposing an alternative to his amendment to strike a 16.4-cent-a-barrel tax on imported petroleum products and foreign oil refined in the United States.

You wouldn't be allowed to do this in professional wrestling. Graham was angry that people would be mistaken if they thought they were dumb.

The debate on the budget reconciliation would behell, warned Graham.

Graham accused his colleague of faking drama after she proposed an amendment to strike the surcharge on barrels of oil moments after she voted against his amendment to repeal the surcharge.

The key difference was that Graham's amendment was set at a 50-vote threshold and had a chance of passing if one Democrat voted "yes" while Hassan's amendment had to overcome a 60-vote threshold and therefore had no chance of becoming part of the bill.

Graham accused Hassan of trying to look good for the voters by voting for repeal of the gas tax despite voting against it.

You're doing something that's not right. It's not right. Graham promised that they would call you out.

Murphy stepped in after that attack.

He told them to address each other through the chair and third person.

He said that senators should address their remarks through the chair in the third person.

At the time of the exchange, Murphy could have ordered Graham to take his seat.

The presiding officer has the power to order a senator to stop attacking another senator.

The chairperson of the Senate can order the offending senator to be quiet if a formal rebuke is made.

Graham was calm after Murphy warned.
