Add former White House Press Secretary Dana Perino to the list of current and former political officials on Twitter.

Perino, the press secretary for President Bush during the tail end of his administration, joined Twitter late last night, posting a link to a post she did on National Review Online's blog, in which she challenges the growth of commentary in journalism.

Perino tweeted:
NRO's The Corner: Glass Houses

(Hat tip to the Republican staff of the House Ways & Means Committee, who added Perino to its "Follow Friday" list.)
