POWER OF ATTORNEY
      Know all by these presents, that I hereby constitute and appoint each of Ben G. Campbell
and Troy Renner my true and lawful attorney-in-fact and agent, each acting alone, with full power
of substitution for me and in my name, place and stead, to: 
1.  execute for me and on my behalf, in my capacity as an officer and/or director of 
C.H. Robinson Worldwide, Inc., Forms 3, 4 or 5 in accordance with Section 16(a) of the 
Securities Exchange Act of 1934, as amended, and the rules promulgated thereunder; 
2.  do and perform any and all acts for me and on my behalf which may be necessary or desirable 
to complete and execute any such Form 3, 4 or 5, complete and execute any amendment or amendments 
thereto 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 of benefit to me, in my best interest or legally required 
by me, 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, 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 C.H. Robinson 
Worldwide, Inc. assuming, any of my responsibilities to comply with Section 16 of the Securities 
Exchange Act of 1934, as amended.
      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 securities of 
C.H. Robinson Worldwide, Inc., unless earlier revoked by me in a signed writing delivered to the 
attorneys-in-fact named above.
