The argument was over immigration policy, with Bolton wanting a more hard-line approach on illegal border crossings.
One source described the argument as a "tense exchange" but said that it had blown over, and that it involved the job performance of Homeland Security Secretary Kirstjen Nielsen, a former deputy to Kelly.
Two of President Donald Trump's top aides were not shy to express their opinion about the progress made to stop illegal immigration into the US. This comes a few days after reports emerged that a caravan of migrants was heading towards US' southern border to cross over into the "land of dreams". Nielsen was at the White House for meetings, the sources said, but she was not present for the profanity-filled argument.
"I've not heard about it. No", Trump told reporters Thursday afternoon when asked about the fight, before departing to Montana for a campaign rally.
In response, Sanders said that the Trump team is just "passionate" and "we are not angry". They should be ashamed for pushing an open borders agenda and are only doing this for strictly political reasons.
The efforts faced an enormous pushback from Democrats, who argue that the United States should continue to welcome immigrants to benefit the US economy. According to most recent DHS statistics, a total of 16,658 family members were arrested at the southern border last month, becoming the highest one-month total on record.
