Rep. Jeff Van Drew is considering the switch as he struggles in New Jersey politics. Internal polling has shown he was losing major support from Democrats in the district, Democratic sources told CNN on Saturday. Switching parties would allow Van Drew to avoid a Democratic primary challenge for his seat.
New Jersey Gov. Phil Murphy on Saturday blasted the change, saying Van Drew is "willing to enable Donald Trump just to try to salvage his own election."
"Betraying our values by siding with Donald Trump is the final straw and made it impossible for him to continue being supported by our party, as grassroots activists, local party leaders in his district, and I have made clear in recent weeks," Murphy, a Democrat, said in a statement. "This party switch is cynical and desperate, and I am confident that a Democrat who shares the values and priorities of our Democratic Party will hold this seat."
A senior Republican source also confirmed to CNN on Saturday that Van Drew is expected to switch parties. He has told his staff and met with Trump, according to the source.
The timing of the announcement is not clear but expected this week, according to the source. It seemed to be under discussion whether he would switch before the impeachment vote or if the White House wanted him to vote against impeachment as a Democrat to show a defection.
Van Drew is calling fellow congressional Democrats, including some in the New Jersey delegation, to talk about his decision to switch parties, a source familiar with his plans told CNN. New Jersey Democrats and other Democrats on Capitol Hill are urging Van Drew to stay in the party, according to the source.
In these phone calls, Van Drew has expressed concerns to his colleagues about the blowback he's gotten in the Democratic Party back home over his position on impeachment, the source added.
The move, while a symbolic boost for Trump, likely won't change the outcome of the House vote that would see Trump as only the third president in American history to be impeached.
CNN has reached out to Van Drew's office and the Trump administration for comment. Van Drew, his chief of staff and communications director did not respond to the Post's requests for comment Saturday.
According to the Post, Van Drew denied on Tuesday that he was switching parties.
"I'm not changing anything -- just doing my job. I'm still a Democrat, right here," he told the Post in a brief interview.
After voting against the formal inquiry in October, the New Jersey congressman said in a statement that "without bipartisan support I believe this inquiry will further divide the country tearing it apart at the seams and will ultimately fail in the Senate."
Van Drew replaced a Republican in 2018 to represent New Jersey's 2nd Congressional District, which Trump won in 2016.
Later Saturday, House Minority Leader Kevin McCarthy, a California Republican, welcomed Van Drew to the Republican Party.
"I want to tell Jeff Van Drew that he is welcome in the Republican Party, not just by me but by our conference, and we would support him and we would welcome him to join," McCarthy told Fox News' Jeanine Pirro.
