Trump announced that Republican Senator Mark Meadows would become the new White House chief of staff, replacing Mick Mulvaney.

"I am delighted to announce that Senator Mark Meadows will become White House Chief of Staff," US President Donald Trump wrote on Twitter on March 6. "I have known and worked with Mark for a long time and the relationship is very good," the US President said.

Meadows, 61, is a Republican member and congressman representing the 11th congressional area of North Carolina since 2013. He graduated from the University of South Florida in 1981.

He will become the fourth White House chief of staff during President Trump's term, replacing his predecessor Mick Mulvaney. Mulvaney, 67, was appointed Chief of the White House office in December 2018.

However, Mulvaney last October was said to have angered Trump after a "speechless" speech at the White House. During a press conference on the Trump investigation that pressured Ukraine, Mulvaney denied the allegations by declaring "We do it all the time". He later issued a corrective statement, asserting that there was no collusion between the Trump administration and Ukraine.

In a statement last night, Trump said that after leaving the White House, Mulvaney will become the US ambassador to Northern Ireland and thank him for his "hard work" for the government.

The decision to replace Mulvaney was made as the Trump administration faced Covid-19, which was spreading fast and posed new challenges for his re-election campaign into the White House.
