Sen. John McCain (R-Ariz.) is aiding the 2010 House campaign of Colorado lawyer Lang Sias (R), who oversaw veterans’ issues for McCain’s 2008 presidential campaign.

McCain’s Country First PAC said that Sias, a pilot and Navy veteran who announced last week that he will challenge two-term Rep. Ed Perlmutter (D) in the 7th district near Denver, “has put it all on the line for our country many times. In Congress, as he has done his entire life, he will be a leader on the issues that matter most to Colorado voters and their families.”

The political blog ColoradoPols.com has the full text of a McCain endorsement e-mail that Sias’ campaign circulated Wednesday.
