House Speaker Paul Ryan confirmed Monday that he would step down as chairman of the Republican presidential convention in July if presumptive frontrunner Donald Trump asks him to do so. The move comes amid rising tensions between the pair, as Ryan has been an outspoken critic of the reality-TV star’s campaign rhetoric and has thus far withheld support for his nomination. In return, Trump’s camp has insulted Ryan and top surrogate Sarah Palin has begun a visible effort to back a candidate seeking to oust Ryan from his Wisconsin seat.
