A White House official told Axios and The Washington Post on Saturday that Trump's pledge is not meant as a reimbursement to the Republican National Committee (RNC), which has spent a nearly identical amount on lawyers representing the president and his eldest son Donald Trump Jr.

The official told Axios that the money would be used to "to defray the costs of legal fees for his associates, including former and current White House aides."

The official said Trump's pledge did not preclude him from increasing the amount available for aides in the future, according to the Post.

Trump's move comes amid ongoing probes by special counsel Robert Mueller and the House and Senate Intelligence committees into Russia's attempts to meddle in the 2016 election.

Investigators have heard testimonies from a number of Trump associates, and the legal fees for staffers under scrutiny is expected to increase.

Trump declined to commit to speak with Mueller's team this week, claiming in a Fox Business interview released Friday that "nobody's asked" him to do an interview.
