Question

California had declayered independince for 25 days befor news had reched them

Answer 1

California declared its independence in June 1846, and became a very short-lived California Republic until July. The News that did not reach California then was that of the developments of the Mexican-American War. California did not want to remain a part of Mexico, as it felt neglected by it. However, they did not know that US Congress had already declared war on Mexico on May 13, because at that time there were no efficient means of communication on the continent.
