Sure...

France 24 has a story about UFOs being treated seriously now, and includes this very improbable story:

What officials and scientists aren’t saying is that these are aliens coming from another planet to visit us. They simply don’t know what these objects are, they say. The discussion is still largely couched in distinctly concrete terms and centers around the concern that these craft may represent a threat from enemies here on earth.

At least one official has been willing to go further, though. In December 2020, Haim Eshed, the former head of the space directorate of the Israeli Defence Ministry, told the Yediot Aharonot newspaper that humans have been in contact with extraterrestrials and have signed a co-operation accord with them. 

“There is an agreement between the US government and the aliens,” he told the newspaper. "They signed a contract with us to do experiments here."

Former president Donald Trump was in on the secret, he said, and had been “on the verge of revealing” it but was asked not to due to fears of “mass hysteria”.

Eshed’s assertion doesn’t seem to represent the consensus view in Israel. The chairman of the country’s Space Agency, Isaac Ben-Israel, told the Times of Israel that while the scientific community thinks the chances that there is life in outer space is “considerable, not small,” he doesn’t believe “there were any physical encounters between us and aliens".

I said ages ago that if some government agency had proof of alien presence on Earth that they thought should be kept secret, there is no way they would have told Trump, as he would blurted it out at his next rally and tried to take narcissistic credit for being the person to tell the world.

Update:   Eshed has made other claims:

Eshed makes implausible claims that include stories of how aliens prevented potential nuclear disasters, including an unspecified nuclear incident during the Bay of Pigs Invasion.^[24][25]
