(CNN) President Donald Trump is expected to name David Malpass as the US' choice to lead the World Bank on Wednesday, sources told CNN.

While the announcement is expected Wednesday, the sources cautioned the decision would not be final until the President announced it.

Trump was given the opening early last month, when World Bank President Jim Yong Kim announced his sudden resignation as the head of the organization, whose leader has been appointed by the US president since its inception.

Politico was first to report on Trump's expected choice of Malpass, the current under secretary for international affairs at the Treasury Department.

Malpass went on to become an economic adviser to Trump during the 2016 campaign, his Treasury page states.

Malpass was part of the US delegation that headed to Beijing last month for trade talks.

Trump has railed against multilateral institutions and questioned US foreign aid commitments, and his choice for the World Bank could precipitate a clash with other nations over the US' continued dominance of the global development bank.

Trump was reported to have cast a wide net for candidates to replace Kim, including interviewing Heidi Cruz, an investment banker who's the wife of GOP Sen. Ted Cruz of Texas, who Trump attacked personally during the campaign.
