Donald Trump’s fixer-turned-foe awaits a bruising round of questioning from the former president’s lawyers after testimony that linked the celebrity client to all aspects of a hush money scheme that prosecutors say was aimed at stifling stories that threatened his 2016 campaign. Michael Cohen returns to the stand Tuesday as the prosecution’s star witness, where a day earlier he delivered matter-of-fact testimony that went to the heart of the former president’s trial. He said, for instance, that Trump had promised to reimburse the money he fronted for the payments and was constantly updated about behind-the-scenes efforts to bury stories feared to be harmful to the campaign.

A lawsuit filed by six members of a University of Wyoming sorority who are challenging the admission of a transgender woman into their local chapter will be argued in an appeals court Tuesday. The case is set to be argued before the three-judge U.S. 10th Circuit Court of Appeals in Denver. The sorority sisters argue the sorority ignored its own rules by allowing the transgender woman in the local chapter in Laramie, Wyoming. A judge in Wyoming threw out the lawsuit last year, ruling that he could not override how the private, voluntary organization defined a woman and order that she not belong.

The United Nations says more than half a million Palestinians have been displaced in recent days by escalating Israeli military operations in both southern and northern Gaza. Aid workers are struggling to distribute dwindling supplies to Palestinians in makeshift tent camps facing catastrophic levels of hunger. The United Nations’ agency for Palestinian refugees says around 450,000 Palestinians were driven from the southern Gaza city of Rafah over the past week. The U.N. said Monday that 100,000 people were displaced so far by Israeli evacuation orders in northern Gaza. Israeli forces are battling militants in northern areas despite launching major operations earlier in the war. Palestinian officials say Israeli strikes in central Gaza killed at least 12 people overnight and into Tuesday.
