Speaking to reporters Wednesday, one day after he was captured on tape urging Harper's staff to get him in front of the wall with the prime minister for a photo, Adler said he was joking.
"You guys don't get a joke, huh?" he said to reporters travelling in the Middle East with Harper.
"It's all said tongue-in-cheek," he added.
"Tongue-in-cheek, guys, come on."
The day before, Adler was caught on microphone asking Jeremy Hunt, one of Harper's staffers, whether he could get a photo with Harper in front of the wall, a holy site for Jewish prayer.
'It's the re-election'
"Jeremy, Jeremy," Adler said. "Can we get in?
"No," Hunt replied.
Adler was undeterred.
"This, it's the re-election. This is the million-dollar shot," Adler said.
Adler then asked whether Hunt could get Harper over to shake his hand once he was done at the wall
While Hunt's ultimate response wasn't caught on tape, it doesn't appear Adler got his wish. He later tweeted a photo showing himself and Harper amid a crowd leaving the wall.
Adler is part of Harper's official delegation to Israel and tweeted that he was going to an official state dinner with Israeli Prime Minister Benjamin Netanyahu that night.
He also tweeted about his trip to the Western Wall.
"Incredible experience at the [Western Wall] – one of the most important sites for Jewish people in Canada and around the world," he wrote on Twitter.
Adler is the MP for Toronto's York Centre riding, which counts 21,310 Jewish people among its 113,457 residents, according to 2011 Statistics Canada figures.Suggest a correction
