	abstract = {Let $M$ be a random element of the unitary, special orthogonal, or unitary symplectic groups, distributed according to Haar measure. By a classical result of Diaconis and Shahshahani, for large matrix size $n$, the vector of traces of consecutive powers of $M$ tends to a vector of independent (real or complex) Gaussian random variables. Recently, Jason Fulman has demonstrated that for a single power $j$ (which may grow with $n$),  a speed of convergence result may be obtained via Stein's method of exchangeable pairs. In this note, we extend  Fulman's result to the multivariate central limit theorem for the full vector of traces of powers.},
