POWER OF ATTORNEY
      I hereby constitute and appoint each of Gregory
B. McShea, Anne S. Kochevar, Lisa G. Mrozek and
Randolph L. Kohn, signing singly, my true and lawful
attorney-in-fact to:
(1)	execute for and on my behalf, in my capacity
as a trustee of Western Asset/Claymore U.S.
Treasury Inflation Protected Securities
Fund, a Massachusetts business trust (the
Fund), Forms 3, 4 and 5 in accordance with
Section 16(a) of the Securities Exchange Act
of 1934, as amended, and the rules
thereunder;
(2)	do and perform any and all acts for and on
my behalf that may be necessary or desirable
to complete and execute any such Form 3, 4
or 5 and timely file such form with the
United States Securities and Exchange
Commission and any stock exchange or similar
authority; and
(3)	take any other action of any type whatsoever
in connection with the foregoing which, in
the opinion of such attorney-in-fact, may be
to my benefit, in my best interest, or that
I am legally required to do, it being
understood that the documents executed by
such attorney-in-fact on my behalf pursuant
to this Power of Attorney shall be in such
form and shall contain such terms and
conditions as such attorney-in-fact may
approve in such attorney-in-fact's
discretion.
      I hereby grant to each such attorney-in-fact full
power and authority to do and perform any and every act
and thing whatsoever requisite, necessary, or proper to
be done in the exercise of any of the rights and powers
herein granted, as fully to all intents and purposes as I
might or could do if personally present, with full power
of substitution, resubstitution or revocation, hereby
ratifying and confirming all that such attorney-in-fact,
or such attorney-in-fact's substitute or substitutes,
shall lawfully do or cause to be done by virtue of this
power of attorney and the rights and powers herein
granted.  I acknowledge that the attorneys-in-fact, in
serving in such capacity at my request, are not assuming,
nor is the Fund assuming, any of my responsibilities to
comply with Section 16 of the Securities Exchange Act of
1934, as amended, and the rules thereunder.
      This Power of Attorney shall remain in full force
and effect until I am no longer required to file Forms 3,
4 and 5 with respect to my holdings of and transactions
in Fund securities, unless I earlier revoke it in a
signed writing delivered to the attorneys-in-fact.
      IN WITNESS WHEREOF, I have caused this Power of
Attorney to be executed as of this 21st day of August,
2003.
