Former presidential candidate Sen. Bernie Sanders on Thursday will introduce a 100-percent clean energy bill to kick off major protests against President Trump's environmental agenda this weekend.

The independent senator from Vermont, who ran as a Democrat, will be joined by climate change stalwart Sen. Ed Markey, D-Mass., at a public rally hosted by the organizers of the People's Climate March to announce the bill, according to an agenda.

The bill underscores one of Sanders' 2016 campaign promises to ban the oil drilling practice known as hydraulic fracturing, or fracking. The legislation, which doesn't have much of a chance of passage in the Republican-controlled Congress, calls for transitioning the nation's energy mix from fossil fuels to 100-percent renewable energy by 2050.

On Friday, Markey will convene a pre-protest climate change summit in Washington ahead of the Saturday march.

This weekend's march, compared to last week's science protests, is billed as a day to protest Trump's environmental agenda on his 100th day in office.

"On the 100th day of the Trump administration, we will be in the streets of Washington, D.C., to show the world and our leaders that we will resist attacks on our people, our communities and our planet," according to the People's Climate March website.
