The campaign added that O'Rourke's decision to release his returns "follows his commitment to increasing accountability and transparency while in the House of Representatives when he held monthly public town halls back in his district where any person could ask any question."

In 2017, O'Rourke and his wife, Amy, had adjusted gross income of $366,455 and paid $81,019 in taxes, for an effective tax rate of 22.1 percent.

The O'Rourkes reported $1,166 in charitable contributions, $1,000 of which went to Annunciation House, which helps migrant, homeless and economically vulnerable people in the El Paso-Juarez area.

O'Rourke became the latest of several 2020 candidates to release his financial information amid an intensified push from Democrats to obtain President Trump's tax returns. Sen.

Trump has yet to publicly disclose his returns, saying that he is under audit and won't release his taxes until he isn't, though the IRS has publicly said an audit in no way prevents Americans from disclosing their tax info.
