President Trump has ordered the Department of the Interior to review all designations of national monuments greater than 100,000 acres created since 1996.

Advocates for rebuilding America’s decrepit infrastructure are beginning to worry that the Trump administration will not follow through on its promise to invest $1 trillion in upgrading the nation’s rails, roads, bridges and transit.

When Chris Ategeka was a boy of 7 in Uganda, his parents died of HIV/AIDS. And his brother, not yet 5, died of malaria.

Today he's 32. He's got a degree in mechanical engineering from the University of California, Berkeley (where he was the commencement speaker for the college of engineering at his graduation in 2011). With his entrepreneurial spirit, he could have followed classmates to Silicon Valley.

But he didn't.

In his TED Fellows talk in Vancouver this week, he explained how his personal history set him on a different path.

Gerald Chinchar, a Navy veteran who loves TV Westerns, isn't quite at the end of his life, but the end is probably not far away. The 77-year-old's medications fill a dresser drawer, and congestive heart failure puts him at high risk of emergency room visits and long hospital stays. He fell twice last year, shattering his hip and femur, and now gets around his San Diego home in a wheelchair.

Above all, Chinchar hopes to avoid another long stint in the hospital. He still likes to go watch his grandchildren's sporting events and play blackjack at the casino.

President Trump signed an executive order Friday that aims to expand offshore drilling for oil and gas, in a move welcomed by the oil and gas industry and greeted with alarm by environmental groups.

"Renewed offshore energy production will reduce the cost of energy, create countless new jobs, and make America more secure and far more energy independent," Trump said before signing the document. He said previous restrictions on exploration and production deprive the U.S. of "potentially thousands and thousands of jobs and billions of dollars in wealth."
