Sell-off in industrial, tech stocks sends Dow down 400
NEW YORK (AP) - After a strong start, U.S. stocks abruptly sold off Tuesday after machinery maker Caterpillar said it doesn't expect to top its first-quarter profit for the rest of the year. The Dow Jones industrial average plunged as much as 619 points as investors feared that rising oil prices and other costs will slow down growth in company profits. Stocks climbed in early trading as companies like Caterpillar, appliance maker Whirlpool, and Fifth Third Bancorp posted strong quarterly results. Then Caterpillar executives told analysts on a conference call in the late morning that they don't expect the company to report a larger per-share profit for the rest of 2018.

Watchdog report points to power struggle involving VA pick
WASHINGTON (AP) - A watchdog report ordered in 2012 by Dr. Ronny Jackson - President Donald Trump's nominee to lead the Department of Veterans Affairs - found that he and a rival physician exhibited "unprofessional behaviors" as they engaged in a power struggle over the White House medical unit. The report, reviewed Tuesday by The Associated Press, suggested the White House consider replacing Jackson or Dr. Jeffrey Kuhlman - or both. Kuhlman was the physician to President Barack Obama at the time. The six-page report by the Navy's Medical Inspector General found a lack of trust in the leadership and low morale among staff members, who described the working environment as "being caught between parents going through a bitter divorce." "There is a severe and pervasive lack of trust in the leadership that has deteriorated to the point that staff walk on 'eggshells,'" the report found.

Trump warns: Iran will pay if it restarts nuclear program
WASHINGTON (AP) - Weighing U.S. withdrawal from the Iran nuclear accord, President Donald Trump declared on Tuesday that if the Iranians "restart their nuclear program, they will have bigger problems than they've ever had before." Trump issued his warning alongside French President Emmanuel Macron in the Oval Office, where the two allies discussed the multinational nuclear agreement, the war in Syria and trade issues during a day of meetings at the White House. Speaking at a joint news conference Tuesday, Trump appeared to be more in line with Macron's push for a longer-term U.S. presence in Syria. Trump, who announced weeks ago that he would withdraw American troops, said Macron reinforced the idea of a potential Iranian takeover of territory liberated from the Islamic State group.

Trump, top Iran diplomat trade threats as US decision nears
NEW YORK (AP) - President Donald Trump and Iran's top diplomat traded sharp warnings on Tuesday, with Trump threatening "bigger problems" than ever if Tehran restarts its nuclear program. Foreign Minister Mohammad Javad Zarif put the president on notice, telling The Associated Press if the U.S. pulls out of the nuclear deal, Iran "mostly likely" would abandon it, too. In a wide-ranging interview, Zarif said a U.S. withdrawal from the landmark 2015 accord would undermine Trump's talks with North Korea by proving that America reneges on its promises. He said if Trump re-imposes sanctions, "basically killing the deal," Iran would no longer be bound by the pact's international obligations, freeing it up to resume enrichment far beyond the deal's strict limits.

In big shift, Trump assesses Kim Jong Un as 'very honorable'
WASHINGTON (AP) - President Donald Trump on Tuesday said Kim Jong Un wants a historic, high-stakes meeting as soon as possible and suggested the North Korean dictator has been "very open" and "very honorable," a sharply different assessment of a leader he once denounced as "Little Rocket Man." The United States and North Korea have been negotiating a summit between Trump and Kim to be held in May or June to broker a deal on Pyongyang's nuclear program. Trump, who has struck a decidedly optimistic tone on the situation in recent days, said Tuesday that the United States and North Korea were having "good discussions."

Canada van victims include people from Jordan, South Korea
TORONTO (AP) - The first victim publicly identified after a van plowed down a Toronto sidewalk and killed 10 people worked at an investment management firm and enjoyed sports and volunteering. Other victims included a Seneca College student, a citizen of Jordan and two Korean nationals, though the names of most of the victims weren't immediately released. Anne Marie D'Amico, 30, worked at Invesco, which is near the scene of Monday's incident. Toronto City Councilor Cesar Palacio said D'Amico was a friend of his daughter, and he remembers her as "a brilliant young girl" who was interested in improving society. On Tuesday he spoke with her parents, who live in his ward.

The Latest: Police officer says most victims of attack women
A Toronto police official says that women make up most of the victims of the deadly van attack but it's not yet known if they were deliberately targeted. Toronto Police Services Det. Sgt. Graham Gibson says the 10 people killed and 14 injured were "predominantly" women. But he say he has no indication yet that suspect Alek Minassian was directing his rented van into women as he plowed into pedestrians in a north Toronto neighborhood on Monday. The issue arose because of what police called a "cryptic" Facebook message posted by Minassian just before the incident that suggested he was part of an online community angry over their inability to form relationships with women.

Police: Co-worker called Waffle House suspect 'paranoid'
NASHVILLE, Tenn. (AP) - The suspect in Sunday's killings at a Tennessee Waffle House once lived in Colorado, where police say a co-worker described him as being paranoid and delusional at times. The co-worker also told a detective the man was infatuated with Taylor Swift and claimed to be a sovereign citizen. Travis Reinking lived in Salida, Colorado, for several months in 2016 and 2017 and worked at a company called Rocky Mountain Crane, Detective Sgt. Rob Martellaro of the Salida Police Department said in a report Monday. One of Reinking's former co-workers told Martellaro that Reinking had identified himself as an anti-government "sovereign citizen" who also disliked the National Rifle Association.
