Cruz held a rally in Brookfield, Wis., following Gov. Scott Walker’s (R) endorsement of the Texas senator one week ahead of the state’s primary. The former presidential hopeful called Cruz "a principled constitutional conservative who can win."
"Now our friend Donald finds debates very, very stressful," Cruz continued. "They make his hair stand on end."
Cruz has repeatedly called on Trump to debate him as the GOP field continues to winnow.
The GOP presidential candidates are scheduled to participate in a CNN town hall on Tuesday night. Cruz has suggested combining the separate interviews into a Trump-Cruz debate.
On Tuesday morning, Trump threatened to skip the network's town hall and accused CNN reporters of treating him unfairly.
"We’re in the same location. They got the TV cameras; they got the moderators ... the one thing they’re missing is The Donald," Cruz said.
"Donald prefers to communicate in 140 characters or less," he said.
"The people of Wisconsin deserve a real debate," Cruz added. "Donald’s absence speaks even louder than his presence."
Cruz and Trump are in a tight race in the Badger State as the Texas senator seeks to close the gap in delegates.
Cruz leads by less than a point in Wisconsin, according to RealClearPolitics.
