CD v. T-bill yields

[colgin]

It has always been my understanding that for the same duration period, CDs from banks yield mpre than T-bills since while CDs are considered extremely safe, by definition Treasuries are safer as they are backed by the full faith and credit of the U.S. governemnt.

Today I looked at my local bank (Chase) for their CD ates and they were offering 2.8% (APY) for 3 months. (I know higher rates are out there but most are between 2.8 - 3.0% with some internet based banks being still higher.) The 3 month T-bill yield as of today closed at 3.33%. Why would I invest in the CD instead of the T-bill. I am sure I am missing something very obvious but would greatly appreciate it if someone could explain this to me.

Thanks.
