Heidi Cruz will not be stumping on husband Ted Cruz's behalf Wednesday in Haddon Heights, New Jersey.
The Cruz campaign has postponed the rally and fundraiser, originally slated to occur at The Cabin on Lippincott Lane, until sometime after the April 5 Wisconsin primary.
"Right now, the Wisconsin demands are too much to be there," said Steve Lonegan, chairman of the Republican hopeful's New Jersey campaign. "We're just going to push this back. Hopefully, we'll have a date for you guys within the next 24 hours."

The postponement comes as Cruz faces tabloid allegations that he has had five extramarital affairs. Cruz denied the report, published by the National Enquirer, as "complete and utter lies" and blamed GOP front-runner Donald Trump for using "enlisted henchmen" to smear his name.
Trump has denied pitching the story to the Enquirer.
Earlier last week, Heidi Cruz found herself caught in the campaign crossfire as her husband sparred with Trump after an anti-Trump group released an ad displaying a provocative photo of the GOP front-runner's wife, Melania Trump. Later Trump retweeted an unflattering photo of Heidi Cruz juxtaposed a Melania Trump glamour shot.
The New Jersey primary take place June 7. Fifty-one delegates are up for grabs in the state's winner-take-all primary.
