(CNN) The unmistakable roar of the A-10's powerful engines echoed throughout Arlington National Cemetery this month as four aircraft saluted retired Col. Avery Kay for the last time with a rare flyover of the historic burial site. Kay, 96, died on October 29 and was buried with full military honors. A highly decorated navigator who led some of the most dangerous bombing raids against Germany during World War II, Kay was also credited with launching the concept of the A-10 Thunderbolt, better known as the Warthog. Despite lacking the air-to-air combat ability of the F-15 Eagle and the high-tech stealth capabilities of the F-22 Raptor, the U.S. Air Force still uses the A-10 to support ground forces in close combat more than 40 years after its first flight in 1975.U.S. Air Force has used A-10 to support ground forces in close combat since 1975Retired Col.

Washington (CNN) If Donald Trump's campaign aides like Paul Manafort were contacting Russian officials during the campaign, then the President had nothing to do with it, claims former Trump campaign manager Corey Lewandowski. "If anybody crossed a line and gave information to a foreign agent or foreign government or foreign intelligence official, whether that's Paul Manafort or it's Rick Gates or anybody else, I hope they're held accountable," Lewandowski told David Axelrod on "The Axe Files," a podcast from the University of Chicago Institute of Politics and CNN. He later added: "Any staffer who contacted or potentially contacted a Russian agent or a Russian official has done so on their own accord and not at the direction of the campaign, the President or anybody else in the administration."Lewandowski attempted to shield the PresidentManafort has denied the alleged contact as "100% not true" 
 Question:Lewandowski and _ were considered part of two rival power centers in the campaign during the time they overlapped.

(CNN) If there is one thing we can count on Donald Trump to deliver, it is controversy. From the day his campaign began, the Republican front-runner has been blunt, outspoken and frequently offensive. Now, just as Trump is attempting to present a more presidential image, the GOP has a new Trump-related headache. Activist groups, particularly those representing minorities and women, are pressing major corporations not to sponsor the Republican convention in July. They hope to persuade companies like Microsoft and Google to drop out of sponsoring what is sure to be a contentious event. These groups have the right idea by speaking out against corporate backing for Cleveland. By sponsoring the GOP convention, companies would be providing a platform for Trump's ugly rhetoric. It is bad messaging and poor business strategy for corporations to be seen as promoting the increasingly toxic Trump brand. Over the course of his campaign thus far, Trump has insulted Latinos, immigrants, women, Muslims, Black Lives Matter protesters, disabled people, and journalists.Raul Reyes: Companies face increasing pressure from petitions to "Dump Trump"He says GOP lawmakers are hedging over whether to attend their convention
