Hillary Clinton went on a Twitter tirade Wednesday against Donald Trump, asking the billionaire 20 questions about reported conflicts of interest that he may have if elected.
The Democratic presidential nominee was referencing a Newsweek cover story arguing that the Trump Organization’s international business relationships could make it hard for a President Trump to conduct foreign policy.
In a post on her website, Clinton said that Trump’s career was “full of sketchy relationships with foreign countries.”
The posts comes amid a debate over Trump’s tax returns, which he has declined to make public, citing a pending IRS audit as prohibiting him from releasing his taxes.
In her tweets, Clinton questioned what Trump would make a priority—America or his personal investments.

17. Will your children disclose all of the foreign trips and business deals they've undertaken during the campaign, and with whom they met?

19. In sum, how will Trump guarantee that if forced to choose between America's security and his own bank account, he won't pick the latter?
— Hillary Clinton (@HillaryClinton) September 14, 2016
20. It's pretty clear: Trump's spent his life unscrupulously looking out for his own wallet above all. Why would that change as president?
