Rep. Tom Tancredo (R-Colo.) sent a letter to John McCainJohn Sidney McCainTrump's dangerous Guantánamo fixation will fuel fire for terrorists Tech beefs up lobbying amid Russia scrutiny Ad encourages GOP senator to vote 'no' on tax bill MORE Tuesday criticizing the Arizona senator for holding a closed-door meeting with Hispanic leaders in Chicago last week.

Calling reports of the meeting "troubling" given McCain's "past sponsorship of amnesty legislation," Tancredo asks McCain if the meeting was a sign that he plans to break his pledge to postpone comprehensive immigration in favor of border security provisions.

Tancredo also urges McCain advocate a security first approach to immigration when he speaks at the National Council of La Raza in July.

"I challenge you to deliver a message to that assembly which does not pander to their amnesty agenda," Tancredo writes. "You should speak to the La Raza convention and to all Hispanic audiences about America's need for secure borders as a priority above all other immigration reforms."

"Senator, you have said many times in recent months, 'I got the message' on border security.
Dear Senator McCain:

Recently in Chicago, you had a closed door meeting with a group of Hispanic leaders. Strangely, the closed door meeting was not on your official events calendar, no press was invited and no press release appears to have been issued.
