In various media appearances in recent days, Netanyahu has accused foreign governments of being "part of a worldwide campaign" to uproot him from power, without pointing the finger specifically at the United States.
"It's confirmed that there is a bipartisan Permanent Subcommittee inquiry into OneVoice's funding of V15," the source was quoted as saying by FOX News.
Additionally, around the same time the partnership between two grassroots movements was announced, US President Barack Obama's former deputy campaign director Jeremy Bird travelled to Israel to assist V15, according to FOX News.
An early general election in Israel is scheduled for Tuesday, March 17. The two main rivals are the largest parties – Likud, headed by Netanyahu, and the opposition Zionist Union, led by Isaac Herzog.
The last poll of the Israeli election campaign released on Friday showed the Zionist Union winning more seats in the Israeli parliament than Likud.
