WASHINGTON House Speaker Paul Ryan (R-Wis.) on Thursday called on Montana Republican House candidate Greg Gianforte to apologize after body-slamming a reporter for asking him a question .

There is no time where a physical altercation should occur, with the press or between human beings, Ryan said at his weekly press briefing. So that is wrong, and it should not have happened.

Police charged Gianforte for assaulting Guardian reporter Ben Jacobs Wednesday night , when Jacobs was trying to ask him a question about the GOPs Obamacare repeal bill.

Fox News reporters present during the altercation backed up Jacobs account. But Gianfortes campaign released a statement disputing the account and accusing Jacobs instead.

Ryan said Gianforte should apologize directly, but stopped short of saying Gianforte should withdraw or resign if he wins Thursdays race.

I know he has his own version, and Im sure hes going to have more to say, but theres no call for this, no matter what, under any circumstance, he added.

Ryan said it is not our choice, when asked whether he would seat Gianforte, if elected to Congress.

If he wins, he has been chosen by the people of Montana,he said. Ill let them decide who they want as their representative.

I do not think this is acceptable behavior, the speaker added.

Meanwhile, House Minority Leader Nancy Pelosi (D-Calif.) on Thursday called the incident outrageous, asking how do you explain this to children?

She also compared Gianfortes behavior to that of President Donald Trump , who bullied and mocked reporters during his campaign, and attempted to infringe on press freedoms .

To see this person, who wants to be the one representative into the House of Representatives from Montana, be sort of a wannabe Trump, Pelosi said. You know, use language like that, treat people harshly like that. Thats his model. Donald Trump is his model.

Gianforte has closely linked himself to Trump as part of his campaign. Trump lent his support to the candidate, recording a robocall for Gianforte, as he faces a close race against Democrat Rob Quist for Montanas lone House seat. The presidents son, Don Jr. , campaigned with Gianforte last month.

The White House on Thursday would not comment on the incident.
