  • President Trump warns Iran in a late Sunday night tweet to 'never, ever' threaten the United States again, or 'suffer the consequences' 
  • Trump calls the controversy over Russia 'a big hoax' after a week of backlash and damage control following his summit with Vladimir Putin
  • EXCLUSIVE: House Republicans asked President Trump to declassify key parts of the surveillance application for ex-campaign adviser Carter Page, according to documents obtained by Fox News
  • The operator of the duck boat in tragic accident that left 17 people dead last Thursday previously warned about safety issues and design flaws, a mechanical inspector says

THE LEAD STORY - HAIL OF GUNFIRE IN TORONTO: Authorities in Toronto late Sunday responded to a mass shooting in the city's neighborhood known as Greektown, where 14 people were hit by gunfire, including at least one fatally ... Responding police exchanged gunfire with the shooter and the suspect was killed. It is unclear if the suspect was hit by police fire. Authorities said it is too early in the investigation to determine if there is a terrorism link. Toronto police chief Mark Saunders said, "Other than the shooter we have a young lady that is deceased." Toronto police tweeted late Sunday that the condition of the victims is not known, but a 9-year-old girl is listed in critical condition. Thirteen others are being treated at a nearby hospital.

WAR OF WORDS: President Trump and Iranian President Hassan Rouhani are now in a war of words. Trump warned Rouhani in a late Sunday night all-capped tweet that he will face dire consequences if he continues to threaten the United States ... "NEVER EVER THREATEN THE UNITED STATES AGAIN OR YOU WILL SUFFER CONSEQUENCES THE LIKE OF WHICH FEW THROUGHOUT HISTORY HAVE EVER SUFFERED BEFORE," the president tweeted. 

The tweet came on the heels of Rouhani’s warning to Trump that hostile policies could lead to the “mother of all wars" with Iran. He earlier warned Trump to stop "playing with the lion's tail" and threatening Iran, "or else you will regret it." Trump earlier this year pulled the United States out of the international deal meant to prevent Tehran from developing a nuclear weapon and ordered increased American sanctions.

'ALL A BIG HOAX': President Trump capped a week of contradictory statements about Russian activities during the 2016 presidential campaign by tweeting, "it is all a big hoax" Sunday evening ... "So President Obama knew about Russia before the Election," Trump tweeted. "Why didn't he do something about it? Why didn't he tell our campaign? Because it is all a big hoax, that’s why, and he thought Crooked Hillary [Clinton] was going to win!!!"

It was not clear precisely what Trump considered a hoax -- the ongoing investigation into whether his campaign colluded with Russian officials, or the notion that Russia had interfered with the election campaign at any point. However, the tweet echoed comments he made in an interview with Fox News' Sean Hannity that aired Monday.

FOX NEWS EXCLUSIVE: DISSECTING THE CARTER PAGE FISA APPLICATION - Republicans on the House Intelligence Committee asked President Trump last month to declassify key sections of the surveillance warrant application for ex-campaign aide Carter Pageaccording to a letter obtained by Fox News ... The heavily-redacted application outlining the justifications for surveilling Page, which was approved and renewed several times by the Foreign Intelligence Surveillance Court (FISC), was released over the weekend after a Freedom of Information Act lawsuit. “Because DOJ (Department of Justice) and FBI continue to obstruct the Committee's investigation, it is time to put the facts in the public domain,” the letter, dated June 14, states.

OVERLOOKED WARNING SIGNS: A mechanical inspector said Sunday he warned the company operating the now-capsized duck boat in Missouri about massive design flaws and dangerous safety issues almost a year before Thursday's tragic accident that killed 17 people and injured seven others ... "My first thought was I was thankful that me and my family weren't on the ducks," Steven Paul told Fox News. "My second thought was, 'Oh man, I probably inspected that boat.'" Paul, who served in the U.S. Army for 6 years as a diesel mechanic before opening Test Drive Technologies in 2009, told Fox he was hired by Ripley Entertainment last year to inspect 24 duck boats.

Paul said he sent the company a "2-to-3-page fleet inspection report" as well as 24 checklist reports and "as many as 20 photos for each duck" he inspected in August 2017. In the report, he cautioned that the boats' engines -and pumps that remove water from their hulls- might fail in bad weather.
