According to a White House official cited by Axios, Trump expects Zelensky to stick to his cease-fire proposal, which would initially stop Ukrainian and Russian attacks on refineries. However, Russia did not agree to the proposal, and Zelensky said that Trump's ceasefire announcement was news to him. A senior White House official said the cessation of attacks on refineries could pave the way for a broader agreement that would cover power plants and power grids. Source: Axios
