The first group to sue President Trump over his proposed border wall reached a record high this week of 68 lawsuits filed against the administration’s environmental policies.

That’s a little more than one lawsuit per week from the time Trump was sworn in, according to the Center for Biological Diversity.

“Trump has been in office 65 weeks,” and the group “has sued him 68 times for killing endangered species, trashing climate policy, poisoning children and farm workers, hiding public documents and his border wall,” tweeted Kieran Suckling, the group's executive director.

The group began its litigation campaign by suing the Department of Homeland Security over the proposed path of Trump's proposed border wall. They argue the wall would cross through protected wildlife areas key to species migration.

“From the moment he took office, our lawyers have been working feverishly to oppose every attempt he's made to worsen climate change, kill wildlife, endanger public health and destroy public lands,” the group said in updating its official lawsuit tracker Monday.

“The Center for Biological Diversity is resisting Trump in every way possible — especially in the courts,” it added.

Lawsuit number 68 was filed in U.S. District Court in Boise on Monday in a lawsuit with other environmental groups challenging the administration’s policies that gut protections for the greater sage grouse, while allowing crude oil and natural gas leases to move forward in the birds' prime habitat.

The lawsuit argues that the Interior Department’s Bureau of Land Management violated the National Environmental Policy Act and Federal Lands Policy and Management Act “when it approved eight massive oil and gas lease sales in Nevada, Utah, Montana, Wyoming and Idaho."
