WASHINGTON - Republican New Jersey Governor Chris Christie, days before he is to formally announce he is running for US president, tweeted a link on Saturday to a website touting his campaign.Featuring the slogan "Telling it like it is," the site, www.chrischristie.com, has slots for supporters to sign up and a button for donations."Are you ready? Sign up. Donate. And help in our effort to keep #TellingItLikeItIs chrischristie.com," the governor said on Twitter.Christie, 52, is expected to announce on Tuesday that he will seek the Republican nomination for president in 2016, a source familiar with his plans said on Thursday.Christie, a controversial figure in New Jersey politics seen as honest and plain spoken by supporters and a bully by detractors, will be joining more than a dozen Republicans already in the race for the party's nomination.
