PolitiFact

Fact-checking journalism is the heart of PolitiFact. The core principles are independence, transparency, fairness, thorough reporting and clear writing. The reason we publish is to give citizens the information they need to govern themselves in a democracy.

Since their launch in 2007, they’ve received many questions about how we choose facts to check, how we stay nonpartisan, how we go about fact-checking and other topics. This document attempts to answer those questions and many more.

El Sabueso

Fooling a dog is difficult. He uses his sense of smell, his sight, he digs in the ground. With his senses he discovers everything ... even the lies of a politician. On Wednesday, January 28, 2015, Animal Político started its speech verification project called El Sabueso to contribute to monitoring the public debate. El Sabueso will analyze a phrase of relevance to national life and, with hard data, will establish whether it is true or false. This type of journalistic exercise is known as fact-checking and has been a trend in Latin America for several years.
