The U.S. Justice Department is investigating whether a fugitive Malaysian financier laundered tens of millions of dollars through two associates and used the funds to pay a U.S. legal team that includes former New Jersey Gov. Chris Christie and a lawyer who represents President Trump, according to people familiar with the matter.

Jho Low, the Malaysian businessman, has been described in U.S. court filings as playing a central role in the alleged embezzlement of $4.5 billion from a Malaysian fund called 1Malaysia Development Bhd.
