Republican presidential nominee Donald Trump cancelled scheduled campaign events in Colorado, Nevada and Oregon in a week that was originally billed by the campaign as focusing on immigration.

While Trump will attend a private fundraiser in Aspen, Co. he will not make a speech on immigration that was scheduled in Denver on Thursday, according to the Denver Post.

The Trump campaign also said it had cancelled a planned rally in Las Vegas on Friday, according to local ABC affiliate KTNV. No reason was given for the Nevada cancellation, but a planned Lake Tahoe fundraiser will continue as planned.

Another planned rally and fundraiser in Portland, Ore., scheduled for Aug. 31, was cancelled, according to local CBS affiliate KOIN. Trump’s Oregon campaign director, Jacob G. Daniels, cited Trump’s visit to Baton Rouge, La., which has been ravaged by heavy flooding, as the reason for the cancellation.

Trump’s new campaign manager Kellyanne Conway told CNN on Thursday that these events would be part of “immigration week,” where the billionaire would hone in on his message via policy speeches.

The GOP is struggling with Hispanic voters as Trump continues to make anti-immigrant comments on the campaign trail.
