“I submit a report on the admission of the Republic of Finland to the North Atlantic Treaty Organization,” the letter says.

A letter with similar content was sent by Biden to congressional committees regarding Sweden's joining the alliance.

It is noted that the congress, according to the procedure, needs to ratify the decision to admit new members to the alliance.

On June 29, the leaders of the member countries of the alliance decided to invite Sweden and Finland to become members of the military association.

NATO Secretary General Jens Stoltenberg announced the signing of a protocol on the accession of Sweden and Finland to the alliance on July 5.
