The New York state attorney general sued U.S. President Donald Trump, three of his children and his foundation on Thursday, saying he illegally used the nonprofit as a personal "checkbook" for his own benefit, including his 2016 presidential campaign.

Barbara Underwood, the attorney general, asked a state judge to dissolve the Donald J. Trump Foundation and to ban Trump, his sons, Donald Jr. and Eric, and his daughter, Ivanka, from holding leadership roles in New York charities. The three children joined the foundation's board in 2006, although Ivanka stepped down to work at the White House in 2017.

Underwood said her office's 21-month investigation, begun under her predecessor, Eric Schneiderman, uncovered "extensive unlawful political coordination" by the foundation with Trump's campaign, as well as "repeated and willful self-dealing" to benefit Trump's personal, business and political interests.
