Good morning, US politics blog readers. Donald Trump is today heading to East Palestine, Ohio, where a Norfolk Southern train carrying toxic chemicals derailed earlier this month, causing an environmental disaster and an intensifying political firestorm. Trump wants to seize the initiative from Joe Biden, who Republicans have criticized for not visiting the Ohio town, though he did dispatch his Environmental Protection Agency (EPA) chief. But Trump, who is running for president once again, may have questions of his own to answer in East Palestine. During his four years in the White House, he loosened up safety regulations for rail operators, and tried to curb the EPA’s powers.

Here’s what else is going on today:

Biden continues his visit to Poland, where he’ll be meeting with the leaders of America’s eastern European allies and Nato secretary general Jens Stoltenberg, before flying back to Washington later today.

The supreme court will hear the second of two cases that address the question of whether tech companies are liable for users’ online speech.

Kamala Harris will be in Maryland to talk about the Biden’ administration’s efforts to lower costs for homebuyers.
