President Trump and his Republican allies remained defiant in spate of violence in the United States

President Trump and his Republican allies remained defiant Sunday amid allegations from critics that Trump’s incendiary attacks on political rivals and racially charged rhetoric on the campaign trail bear some culpability for the climate surrounding a spate of violence in the United States.

Trump, who has faced calls to tone down his public statements, signaled that he would do no such thing — berating billionaire liberal activist Tom Steyer, a target of a mail bomb sent by a Trump supporter, as a “crazed & stumbling lunatic” on Twitter, after Steyer said on CNN that Trump and the Republican Party have created an atmosphere of “political violence.”

Thomas Fahr Steyer is an American billionaire hedge fund manager, philanthropist, environmentalist, liberal activist, and fundraiser. Steyer is the founder and former co-senior managing partner of Farallon Capital and the co-founder of Onecalifornia Bank, which became Beneficial State Bank, an Oakland-based community development bank. Farallon Capital manages $20 billion in capital for institutions and high-net-worth individuals. The firm's institutional investors include college endowments and foundations. Since 1986, Steyer has been a partner and member of the Executive Committee at Hellman & Friedman, a San Francisco–based $8 billion private equity firm.
