(Oracle, AZ)  --  An Arizona Republican who's running for Congress is red-faced after he mistook a school bus filled with YMCA kids for undocumented immigrants. 

State Representative Adam Kwasman was near a housing facility for migrants yesterday when he posted a picture of the bus to Twitter along with the stern warning "This is not compassion.  This the abrogation of the rule of law." 

He later told a reporter he could see "the fear" in the children's faces.  When the reporter informed Kwasman that the kids on the bus were heading to a YMCA camp near Tucson, he insisted "they were sad too." 

Kwasman later deleted his tweet.
