The new website —www.chrischristie.com — shows the New Jersey governor's name along with the slogan, "Telling it like it is."
And there's a short animated video posted on Christie's Twitter feed that promotes the new campaign site.
The site says it's paid for Chris Christie for President, Inc.
Donors and friends are getting invitations to Christie's campaign announcement event Tuesday at his former high school.
Christie will be the 14th Republican candidate to seek the nomination.
