New York (CNN Business) Campbell Soup has disavowed claims made by a company lobbyist that George Soros' foundation is assisting a caravan of migrants bound for the United States.

In a tweet sent on Monday, Kelly Johnston, Campbell's vice president of government affairs, wrote that the Open Society Foundations has arranged for "troop carriers" and "rail cars" to support the caravan, which formed in Central America. Johnston's Twitter account has been deleted, and the tweet is no longer online. New York Times reporter Kenneth Vogel posted a screen grab of Johnston's tweet on Tuesday.

"The opinions Mr. Johnston expresses on Twitter are his individual views and do not represent the position of Campbell Soup Company," a company spokesperson said in a statement on Tuesday.

Johnston did not immediately respond to a request for comment from CNN Business.

The Open Society Foundations, which seeks to promote democracy around the globe, dismissed the tweet as false.
