Updated: Vivek Ramaswamy drops out of presidential race ...

Vivek Ra­maswamy has dropped out of the race to win the Re­pub­li­can nom­i­na­tion for US pres­i­dent, cap­ping an al­most year­long for­ay in­to pol­i­tics that vault­ed the biotech en­tre­pre­neur in­to the na­tion­al spot­light.

The Roivant founder, who made a rep­u­ta­tion dur­ing the buildup to pri­maries with his brash com­ments, con­spir­a­cy the­o­ries and ex­treme con­fi­dence, fin­ished fourth in the Iowa cau­cus­es. Im­me­di­ate­ly af­ter he an­nounced the sus­pen­sion of his own cam­paign, he en­dorsed Don­ald Trump — the win­ner in Iowa who, in his words, is the on­ly oth­er “Amer­i­ca first” can­di­date in the elec­tion.
