Ephraim became a
Forum for Democracy member in 2017 and joined its board as treasurer in November 2019, a few months after the previous treasurer,
Henk Otten, had been expelled from the party. It was announced in October 2020 that Ephraim would appear sixth on Forum for Democracy's
party list in the
2021 general election. The following month, newspaper
Het Parool published an article about antisemitic messages in
WhatsApp groups of the party's youth organization. Ephraim and two others were chosen by the youth organization to investigate the matter.
Het Parool reported that Ephraim had before been involved in the expulsion of
whistleblowers after a report by
HP/De Tijd from April, that was also about extremist messages by members of the youth organization. After the revelations about antisemitic messages, several prominent Forum for Democracy members accused party leader
Thierry Baudet of having made extremist comments during a dinner. Ephraim, one of four board members, defended Baudet by saying that Baudet had made provocative statements, but that he is no "fascist, homophobe, or
Nazi sympathizer". A stalemate was reached when two board members backed Baudet and the two others opposed him. A referendum about Baudet's future was subsequently held, and he received the support of 76% of the voting members. Ephraim rose to spot three on the 2021 general election party list due to prominent members leaving Forum for Democracy because of the events.
House of Representatives He was elected member of the
House of Representatives in the March 2021 election with 989
preference votes and was sworn in on 31 March. Ephraim had stepped down as treasurer in January but stayed on as a board member. In the House, he was his party's spokesperson for finances, the euro, and culture, and he served on the following committees: • Art committee • Contact group Germany • Contact group United Kingdom • Committee for European Affairs • Committee for Finance • Public Expenditure committee Ephraim announced on 13 May 2021 that he would leave Forum for Democracy together with fellow MPs
Wybren van Haga and
Hans Smolders due to "a difference of opinion (...) about how to engage in politics". In the previous week, Van Haga had denounced a
Liberation Day poster by the party, which suggested that the Netherlands had lost its post-
WWII freedom due to the
COVID-19 lockdown. Party leader Baudet had refused to apologize for the poster and had called causing controversy an integral part of FvD. The three MPs continued as
independent politicians and formed a caucus called Groep Van Haga. Ephraim also left all committees that he had been a member of with the exception of the Art committee. He was one of the party's in Amsterdam in the
2022 municipal elections. When the collapse of the
fourth Rutte cabinet led to a
November 2023 snap election, BVNL did not include Ephraim in its list of candidates. Ephraim subsequently left Groep Van Haga on 2 August as a result of an internal conflict, and he continued as Lid Ephraim (Member Ephraim), the 21st caucus in parliament. He told he would remain a member of BVNL. == Personal life ==
