Thousands of Central American migrants fleeing poverty and violence packed a bridge connecting Guatemala and Mexico in sweltering heat Saturday as part of a politically charged, U.S.-bound caravan.At one point, several dozen migrants trying to make their way north sang the Honduran national anthem on the edge of the muddy Suchiate River between Tecun Uman, Guatemala, and Tapachula, Mexico.Their journey continued one day after defiant caravan members rushed passed border gates only to be stopped by rows of Mexican riot police who dispersed tear gas and smoke canisters into the crowds.The slow procession north has led President Donald Trump to threaten to cut aid to Central American nations and to send troops to the U.S. border if Mexico failed to stop the surge."Our message is we're not criminals," Honduran migrant Orlean Herrera said. "We're coming over here because we need a better life. That's why we're here." 933

Top North Korean officials warned the United States in a letter that denuclearization talks are "again at stake and may fall apart," sources familiar with the process told CNN.The letter was delivered to US Secretary of State Mike Pompeo, who abruptly canceled his fourth trip to Pyongyang, hours before he was scheduled to depart with his new special envoy Stephen Biegun on Friday, sources said.Three sources with direct knowledge of the North Korean position on denuclearization said the letter stated that Kim's regime felt that the process couldn't move forward because "the US is still not ready to meet (North Korean) expectations in terms of taking a step forward to sign a peace treaty."The US has so far been unwilling to replace the armistice agreement that ended the Korean War with a permanent, legally binding peace treaty, which would require the approval of two-thirds of the US Senate.If a compromise cannot be reached and nascent talks crumble, Pyongyang could resume "nuclear and missile activities," the sources said.The existence of the letter, sent to Pompeo by Kim Yong Chol, the former head of North Korea's spy agency, was first reported by the Washington Post.The Post, which characterized the letter as a "secret" communication, said it wasn't clear how Kim had gotten the letter to Pompeo, but suggested that it may have been sent through its UN mission.However, Pompeo has been relying on other backchannels, as opposed to dealing directly with his diplomatic counterpart North Korean Foreign Minister Ri Yong Ho, one source said."Before and after Pompeo became the Secretary of State, he seemed to be more interested in maintaining and engaging with Kim Yong Chol through a backdoor channel, rather than with his formal counterpart Ri Yong Ho," said the source. 1809

Thursday marks one year since special counsel Robert Mueller was appointed to investigate Russian meddling in the 2016 US election. Mueller took over an investigation that was first opened by since-fired FBI Director James Comey in July 2016, during the campaign.The far-reaching investigation continues -- witnesses are still being interviewed, and trials are scheduled for later this year. As the proceedings have dragged on, the White House has adopted an increasingly hostile tone toward the investigation, which President Donald Trump has repeatedly called a "witch hunt" and a "hoax."Trump tweeted Thursday about his feelings toward the investigation.  671
