又有三名美国共和党人本星期加入2016年总统选举不断增加的参选人行列。
本·卡森星期日接受采访时说，他将争取共和党总统候选人提名。卡森计划星期一在底特律正式宣布参选。
两年前，卡森在一次演讲中批评奥巴马总统的医保方案，并因此而得名。但他将该医保方案与奴役制相提并论，并对同性恋发表负面评论，从而招致批评。
星期一，前惠普公司总裁卡利·菲奥利纳也将宣布参选。麦凯恩参议员2008年竞选总统时，菲奥利纳担任他的经济问题顾问，从中获得一些参与全国政治活动的经验，她本人曾于2010年竞选美国参议员。
2008年的总统参选人、前阿肯色州州长赫克比计划在星期二宣布参选。
The field for the 2016 U.S. presidential election continues to grow with three prominent Republicans entering the race this week.
Ben Carson said in an interview Sunday he will run in the already crowded competition for his party's nomination. He planned a formal announcement at an event Monday in Detroit.
Carson rose to prominence two years ago with a speech criticizing President Barack Obama's landmark health care initiative, but has also drawn criticism for equating that program to slavery and for comments about homosexuality.
Also Monday, former Hewlett-Packard CEO Carly Fiorina was due to announce her candidacy. She has some experience in national politics having served as an economic advisor to Senator John McCain during the 2008 presidential race he lost to Mr. Obama, as well as her own failed 2010 bid for a U.S. Senate seat.
Another candidate from 2008, former Arkansas Governor Mike Huckabee, plans to join the race on Tuesday.
