Republican presidential front-runner Donald Trump has hired another senior strategist to assist his campaign with its full court press for delegates.

The Trump campaign on Monday announced the addition of former Republican National Committee chief of staff Ken McKay to its delegate operations team. McKay will join Trump’s convention manager Paul Manafort and senior political strategist Rick Wiley as they work to develop a more traditional campaign and court the 1,237 delegates Trump needs to win the nomination on the first ballot.
