《明史·列传·卷一百四十一》
薛国观害怕，并且担心牵涉到考核官吏的大典，想方法阻挠他，于是弹劾吏科都给事中沈惟炳、兵科给事中许誉卿，说： 二人是东林党的盟主，跟瞿式耜一起掌握官吏的选拔。
国观惧，且虞挂察典，思所以挠之，乃劾吏科都给事中沈惟炳、兵科给事中许誉卿，言： 两人主盟东林，与瞿式耜掌握枚卜。
Xue Guo Guan was scared, and he was also worried about being involved in the examination ceremony of officials. He tried to find ways to stop it, so he impeached Shen Weijing, assistant of Department of Officials, and Xu Yuqing, assistant of Department of Military Affairs, saying that the two were盟主 (leaders) of Donglin Party, and were selecting officials together with Qushi Si.
