The presidential field for the GOP grew by another two on Monday as Ben Carson the retired neurosurgeon and Carly Fiorina the former executive in technology both announced they had entered the presidential race.

Fiorina a former CEO at Hewlett Packard confirmed that she would run as was widely expected. Her account on Twitter included a link to the campaign website.

The top of the site on Internet for Fiorina carries her slogan of “New Possibilities, Real Leadership.”

Carson announced on Sunday he would run, telling a TV station in Ohio of his intent to seek the GOP presidential nomination ahead of the official launch of his campaign on Monday in Detroit his home town.

He said he was willing to be part of the overall equation and therefore announce my candidacy for the President of the United States.

The two candidates enter into field in the GOP that is quickly growing with another member, former Governor of Arkansas Mike Huckabee, set to announce his candidacy on Tuesday.

Together, Fiorina and Carson add to the Republican Party’s diversity. Fiorina would be the first and quite possibly only Republican female in the race, while Carson would be the Party’s first black candidate.

Fiorina on Monday also released a video one that underscores her criticism of Hillary Clinton the frontrunner of the Democrats. It starts with her watching the recent announcement of Clinton to enter the race.

Fiorina, who is 60, has been for a long time a Clinton critic and her announcement come only a day prior to the release of her new book.

Fiorina is also planning to host a town hall online Monday through video streaming, before starting a swing through the primary states that include South Carolina, New Hampshire and Iowa.

At the same time, a campaign source has said that Carson cancelled an appearance scheduled for Iowa on Monday so he could travel over to Dallas to say goodbye to his sick mother, who has Alzheimer’s disease. A seat that will be left empty at the kickoff event for Carson was reserved for his mother.
