Yes, you can, but the terms of your trust will supersede your will for the bequest if the same asset is left to two different beneficiaries. The asset is considered to be held by and owned by the trust when you transfer it in, so you're not free to give it to anyone else in your will. But a will can control disposition of assets you haven't included in your trust, and you can create a "pour-over will" to transfer into your trust any assets you own at the time of your death if you haven't already done so.
