Former New York City mayor Rudy Giuliani thinks the U.S. government should put geolocating tags on people who are on the FBI’s terror “watch list.”

Speaking with reporters Wednesday following Republican counterprogramming to the Democratic National Convention in Philadelphia, Giuliani responded to a story indicating that one of the terrorists who killed a priest in Normandy was wearing an electronic tag, reportedly placing him under house arrest, Giuliani said that could be a good practice to introduce in the United States.

“I would think that would be an excellent idea,” the former mayor and prominent Donald Trump supporter said. “If you’re on the terror watch list, I think I should know you’re on the terror watch list. You’re on there for a reason.” He then reminded reporters that he put undercover officers in mosques around New York following the 1993 terror attack on the World Trade Center.

When asked about Trump’s remarks earlier in the day calling for Russia to hack Hillary Clinton’s “missing” State Department emails, Giuliani suggested to The Daily Beast that foreign intervention in elections is not uncommon, and alleged that President Obama impacted the outcome of a recent Israeli election.

“I don’t think foreign powers should be intervening in U.S. elections," Giuliani initially said. "Now, the reality of politics is that foreign powers do, and sometimes we intervene in their elections. So, in an idealistic world, the reality is that foreign powers should stay the heck out of our election. We should stay the heck out of their elections,” he said. “But, gosh knows, President Obama was doing everything he could to unseat [Israeli Prime Minister] Bibi Netanyahu. His aides were over there, his pollsters were over there. His fundraisers were giving money to the opposition. America intervened directly in the Israeli election to defeat Bibi Netanyahu."

Earlier, during the press conference, Giuliani said that the Russians should release any emails they may have so as not to be able to have leverage over Clinton in the White House.
