Canada's Prime Minister Justin Trudeau has given the green light for a second time to a $5.5 billion pipeline expansion that has attracted strong opposition from environmentalists and some indigenous groups.

Trudeau, an ardent supporter of green energy, has found himself defending the 620-mile Trans Mountain pipeline expansion since his government first approved it in 2016. The project is meant to bring petroleum from oil sands near Edmonton, Alberta, to tanks in Burnaby near Vancouver on Canada's Pacific Coast.

President Trump officially launched his 2020 reelection bid on Tuesday at a massive rally in Orlando, though much of the event picked up where his 2016 campaign left off.

Trump relished in reliving his unlikely victory two and a half years ago over Democratic nominee Hillary Clinton. As the crowd broke into chants of "lock her up," he teased about still trying to search for missing emails on her private server and the possibility his Justice Department could look into prosecuting the former secretary of state.

About a mile from the museum, workers with the Canadian division of U.S. defense company General Dynamics Corp. are building the eight-wheeled, amphibious vehicles for Saudi Arabia's National Guard.

In Florida, Gov. Ron DeSantis signed a bill last week that, if federal authorities give it their go-ahead — still a very big if — would allow his state to import prescription drugs from Canada. That makes Florida the third state to pass such a law, joining Vermont and Colorado. More such legislative attempts are in the works.

Remember Boaty McBoatface? In the years since the naming snafu over a research vessel grabbed international headlines, Boaty has been off gathering crucial deep-sea data on the effects of climate change.

Now, the findings from Boaty's first mission are out — and they shed light on how Antarctic winds that are strengthening due to climate change are impacting sea levels.

But before we dive into what Boaty found, let's remember how it got here.
