Washington (People’s Daily)  - Two of US President Donald Trump’s closest advisers, the Chief of Staff John Kelly and the National Security Adviser John Bolton, got into an intense shouting match Thursday at the White House over immigration policies, according to people close to the situation.

The blowup between these two people was loud enough to be overheard by several officials in the West Wing. Kelly and Bolton were sparring over an issue that has frequently angered the president and has often prompted him to lash out at Kirstjen Nielsen, who succeeded Kelly as the secretary of homeland security after serving as his deputy chief of staff in the White House. Bolton was siding with the president, who has angrily blamed Nielsen for failing to staunch the flow of migrants across the border, while Kelly, who is fiercely protective of his protégé, defended her, people said.

"While we are passionate about solving the issue of illegal immigration, we are not angry at one another,” White House Press Secretary Sarah Sanders said in a statement Thursday. “However, we are furious at the failure of Congressional Democrats to help us address this growing crisis.” Trump, while on his way to a rally in Montana, said he had "not heard about" the incident.

The clash is an indication that tension is flaring in the White House 19 days before midterm elections in which Republican control of Congress is at stake. According to CNN’s report, the shouting match was so intense that other White House aides worried one of the two men might immediately resign.
