    公权字诚悬。幼嗜学，十二能为辞赋。元和初，进士擢第，释褐秘书省校书郎。李听镇夏州，辟为掌书记。穆宗即位，入奏事，帝召见，谓公权曰：“我于佛寺见卿笔迹，思之久矣。”即日拜右拾遗，充翰林侍书学士，迁右补阙、司封员外郎。穆宗政僻，尝问公权笔何尽善，对曰：“用笔在心，心正则笔正。”上改容，知其笔谏也。历穆、敬、文三朝，侍书中禁。公绰在太原致书于宰相李宗闵云家弟苦心辞艺先朝以侍书见用颇偕工祝心实耻之乞换一散秩乃迁右司郎中。文宗思之，复召侍书，迁谏议大夫。俄改中书舍人，充翰林书诏学士。便殿对六学士，上语及汉文恭俭，帝举袂日：“此浣濯者三矣。”学士皆赞咏帝之俭德，唯公权无言，帝留而问之，对日：“人主当进贤良，退不肖，纳谏诤，明赏罚。服浣濯之衣，乃小节耳。”时周墀同对，为之股栗，公权辞气不可夺。帝谓之曰：“极知舍人不合作谏议，以卿言事有诤臣风彩，却授卿谏议大夫。”开成三年，转工部侍郎。尝入对，上谓之曰：“近日外议如何？”公权对曰：“自郭旼授邠宁，物仪颇有臧否。”帝曰：“旼，太皇太后之季父，在官无过，自金吾大将授邠宁小镇，何事议论耶？”公权曰：“以旼勋德，除镇攸宜。人情论议者，言旼进二女入宫，致此除拜，此信乎？”帝曰：“二女入宫参太后，非献也。”公权日：“瓜李之嫌，何以户晓？”因引王珪谏太宗出庐江王妃故事，帝即令南内使张日华送二女还旼。公权忠言匡益，皆此类也。
