Laura Bush guest host on "Today" show

First lady Laura Bush will be guest host for an hour of NBC's ''Today'' show next week.

The network said she'll host the 9 a.m. EDT hour April 22, the morning of the Pennsylvania primary. By that time in the four-hour morning show, politics is usually set aside for issues that affect women, who make up the majority of the audience during that time period.

Mrs. Bush will participate in several segments and interviews, NBC said Tuesday.

She will be joined earlier in the broadcast by her daughter Jenna to talk about their new children's book, ''Read All About It!''

The first lady will also give Ann Curry a tour of the Bush family ranch in Crawford, Texas.
