WASHINGTON (Reuters) - Former White House national security adviser John Bolton, who parted ways this week with President Donald Trump, resumed his old job on Friday as head of two political action committees and announced $50,000 in contributions to Republican candidates.

Bolton retook the reins of the John Bolton PAC and the John Bolton Super Pact, two groups he had headed before joining the White House 17 months ago.

Bolton left the White House earlier this week amid simmering differences with Trump on issues such as the U.S. military presence in Afghanistan.

As part of the resumption of his political action groups, Bolton announced the endorsement of five Republicans running in the November 2020 elections.

They are Senator Tom Cotton of Arkansas, Senator Cory Gardner of Colorado, Senator Thom Tillis of North Carolina, U.S. Representative Adam Kinzinger of Illinois and U.S. Representative Lee Zeldin of New York.

Each candidate received $10,000 in contributions from the Bolton groups for a total of $50,000.

“The experience that these incumbent members of Congress have provides them with a remarkable understanding and knowledge of the threats we face from international terrorism and rogue regimes such as Iran and North Korea,” Bolton said in a statement.
