Donald Trump said Wednesday that at least one NFL owner has assured him that his team will stand for the National Anthem before its NFL games.

'Spoke to Jerry Jones of the Dallas Cowboys yesterday. Jerry is a winner who knows how to get things done. Players will stand for Country!' the president tweeted.

Jones knelt along with head coach Jason Garrett and all their players in the middle of the field on Monday night in a show of unity before they all stood for the anthem before their 28-17 win over the Arizona Cardinals.

Jones, 74, in the past has criticized NFL players who kneel during the song itself. But taking a knee beforehand drew some booing from spectators. The Cardinals did not kneel but, like the Cowboys, all linked arms.

Trump praised Jones on Twitter as 'a winner who knows how to get things done'

The entire Dallas Cowboys team, including Jones, knelt before the National Anthem was sung before their game Monday night against the Arizona Cardinals ...

... but then the team stood with linked arms during the anthem itseld. From left to right: Byron Bell, Tyron Smith, Dak Prescott, Chaz Green, La'el Collins, Zack Martin and Rod Smith.

Other NFL team owners have supported their players who chose to kneel in protest of racism in America. Some owners explicitly criticized Donald Trump for his denunciation.

NFL Commissioner Roger Goodell also strongly backed the players and criticized Trump for 'an unfortunate lack of respect for the NFL.'

At a news conference in August, Jones said: 'There's no question in my mind. The national anthem is sacred. Our flag is sacred. And our team has demonstrated that.'

Jones has refrained from explicitly supporting Donald Trump but did donate $1 million to his inaugural committee.

The Dallas Cowboys have been nicknamed 'America's Team' since 1978.

The take-a-knee action, inaugurated by ex-San Francisco 49ers quarterback Colin Kaepernick last season, is meant to protest against police treatment of blacks and social injustice.

'That's a total disrespect of everything that we stand for,' Trump said last Friday in an Alabama speech, encouraging owners to act. He added: 'Wouldn't you love to see one of these NFL owners, when somebody disrespects our flag, you'd say, "Get that son of a bitch off the field right now. Out! He's fired."'

On Saturday, Trump echoed his stance.

'If a player wants the privilege of making millions of dollars in the NFL, or other leagues, he or she should not be allowed to disrespect our Great American Flag (or Country) and should stand for the National Anthem,' Trump tweeted. 'If not, YOU'RE FIRED. Find something else to do!'

Kaepernick has not yet commented on how his movement has taken off within the NFL. He is not playing this season after he was not signed as a free agent.
