“I’ll see who it is,” he told moderator Anderson Cooper during a CNN town hall in Milwaukee. "I’m not looking to hurt anybody. I love the Republican Party.”

Trump added he does not expect his Republican presidential primary rivals to back him should he become their party’s standard-bearer.

“I don’t want people to do something against their will,” he said before using Ted CruzRafael (Ted) Edward CruzGianforte halts in-person campaigning after wife, running mate attend event with Guilfoyle Trump administration grants funding extension for Texas testing sites Hillicon Valley: Democrats introduce bill banning federal government use of facial recognition tech | House lawmakers roll out legislation to establish national cyber director | Top federal IT official to step down MORE, who was asked the same question earlier, as an example.

“I could see [Cruz] was having a hard time with a very simple question. I don’t want him to be tormented. I want him to be comfortable. I don’t need his support. I don’t want his support.”

Cruz strongly suggested he would not support Trump as the GOP nominee earlier Tuesday evening, but stopped short of a definitive answer.

“I’m not in the habit of supporting someone who attacks my wife and attacks my family,” he told Cooper during his own town hall appearance.

“That is going beyond the line. I think that our wife and kids should be off limits. They don’t belong in the attacks.”

Cruz and Trump bitterly feuded last week, with each blaming the other for insulting their loved ones.

Donald Trump first accused Cruz of ties with a super-PAC that used a nude photo of his spouse, Melania Trump, in a campaign ad.

He then threatened to “spill the beans” on Heidi Cruz, inspiring the Texas senator to call the businessman a “sniveling coward” in retaliation.

Tuesday’s town hall in Milwaukee comes one week before the Wisconsin GOP presidential primary.

When asked the same question, Gov. John Kasich said he needs to see what happens before he promises to support whomever the GOP nominee is.

"I got to see what happens," Kasich said.

"If the nominee is somebody that I think is really hurting the country and dividing the country, I cant stand behind them. We have a ways to go, lets see how this all folds out."

"All of us shouldn't even have answered that question," Kasich said of the pledge.

Kasich said earlier he'd been "disturbed" by some of the things he'd seen during the campaign. 

"I have to think about what my word and endorsement would mean in a presidential campaign," he said during the CNN town hall. "I want to see how this thing finishes out."

Cruz leads Trump by less than 1 percent in the Badger State, according to the latest RealClearPolitics average of polls.

Trump, however, has a nearly 11-point edge over Cruz nationwide, also leading in delegates with 736 to the Texas lawmaker’s 463.
