Washington (CNN) Democratic presidential candidate Joe Biden unveiled a plan Monday for how his administration would prioritize ethics should he be elected president in 2020, pledging to "ensure that no future president can ever again abuse the office for personal gain."

In a rebuke of the Trump administration, Biden pledges to "restore" ethics in government, "rein in executive branch financial conflicts of interest," and "return integrity" to decision making in his administration.

The ethics plan comes a day after the former vice president's son, Hunter Biden, announced that he will resign at the end of the month from his board role in the management company of a private equity fund backed by Chinese state-owned entities. Hunter Biden has come under scrutiny from President Donald Trump and Republicans for his position on the board, as well as his previous ties to a Ukrainian energy company, which Trump wanted Ukraine's government to investigate -- a move that largely prompted a House impeachment inquiry into the President's conduct. Trump has denied doing anything improper.

There is no evidence of wrongdoing by either Joe or Hunter Biden.

On Sunday, Hunter Biden also pledged to not work for any foreign-owned companies or serve on their boards should his father be elected President, and his father told reporters that his family and associates would not work for foreign companies if he is elected president, saying he would have "build on the squeaky clean, transparent environment" in the White House reminiscent of former President Barack Obama's administration.
