The Donald Trump campaign has canceled a major speech on immigration that reportedly was slated for Thursday amidst renewed confusion on his stance on mass deportation.

A spokeswoman for the Trump operation in Colorado said the campaign had been looking into hosting such an event but the plans had changed, the Denver Post reported Monday. The campaign will not be hosting such an event when Trump swings through the state for a fundraiser, but supporters were told in an email “the speech (Trump) was planning on giving is still being modified,” according to the Post.

NBC News also confirmed the speech had been postponed, but no reason was given for the reversal.

It was reported by Buzzfeed and Univision over the weekend that Hispanic leaders in a closed door meeting with Trump Saturday were told the GOP nominee was going to flesh out his proposal for dealing with the 11 million immigrants in the United States illegally and present it while in Colorado Thursday. According to those in the meeting, Trump appeared to be softening his stance on mass deportation and was open to a plan to legalize millions of undocumented immigrants.

Throughout the GOP primary, Trump took a hard line on mass deportation, saying that the immigrants would be deported “humanely” but that they “have to go.”

Trump is now denying that he is preparing to flip flop on the issue, while his campaign manager Kellyanne Conway has said his position on deportation forces is “to be determined.”
