In this paper, we consider the (partial) symmetric square $L$-function $L^S(s,pi,Sym^2otimeschi)$ of an irreducible cuspidal automorphic representation $pi$ of $GL_r(A)$ twisted by a Hecke character $chi$. In particular, we will show that the $L$-function $L^S(s,pi,Sym^2otimeschi)$ is holomorphic except at $s=0$ and $s=1$, and moreover the possible poles could occur only when $chi^romega^2=1$, where $omega$ is the central character of $pi$. Our method of proof is essentially a (nontrivial) modification of the one by Bump and Ginzburg in which they considered the case $chi=1$.
