Johnson's statement comes amid ongoing investigations by House Republicans into alleged misconduct by the Biden family, which the White House has been accused of obstructing.
Johnson voiced his stance during an appearance on "Fox & Friends Weekend." Alongside him was House GOP conference chair Elise Stefanik, a Republican from New York. The two were questioned about their plans to initiate an impeachment vote.
Johnson stated, "It's become a necessary step." He further explained, "Elise and I both served on the impeachment defense team of Donald Trump twice when the Democrats used it for brazen, partisan political purposes. We decried that use of it. This is very different. Remember, we are the rule of law team. We have to do it very methodically."
Johnson praised the work of the three committees of jurisdiction — judiciary, oversight, ways and means — for their diligent pursuit of evidence. However, he criticized the White House for allegedly obstructing the process by preventing several DOJ witnesses from testifying and withholding thousands of pages of evidence.
Asserting his conviction in the necessity of the impeachment inquiry vote, Johnson said it would enable Republicans to "take it to the next necessary step." He added, "I think it's something we have to do at this juncture."
Johnson's remarks followed statements from several Republicans on Friday, suggesting that a vote to formalize the impeachment inquiry of President Biden could occur before the House of Representatives adjourns for the December recess.
House Rules Committee Chairman Tom Cole, a Republican from Oklahoma, informed reporters that his committee is likely to receive the legislation "sometime next week," setting the stage for a House-wide vote soon after.
Representative Carlos Gimenez, a Republican from Florida, anticipated a House-wide vote "before we will break" on December 15. He expressed his belief that every Republican should support the impeachment inquiry, citing "plenty of smoke there."
These comments were made after a private House GOP Conference meeting, where the three chairmen investigating Biden and his family — Oversight Chairman James Comer, Judiciary Chairman Jim Jordan, and Ways & Means Chairman Jason Smith — reiterated their case for lawmakers.
Republican Study Committee Chairman Kevin Hern, a Republican from Oklahoma, stated that the meeting was held "to see where the votes are and make sure everybody’s communicated with, people have had their chance to understand what an impeachment inquiry is versus impeachment."
Representative Greg Murphy, a Republican from North Carolina, suggested that a vote would likely occur "soon." He contrasted the Republicans' approach to formalizing the impeachment inquiry with the Democrats' handling of former President Donald Trump's impeachment, which proceeded without a House-wide vote.
Former Speaker Kevin McCarthy, a Republican from California, had previously directed the House to open an impeachment inquiry into Biden in September. However, the White House dismissed the probe as illegitimate without a formal vote.
The administration's refusal to cooperate with House investigators' subpoenas has led even Republicans in districts won by Biden in 2020 to support formalizing the inquiry.
Representative David Schweikert, a Republican from Arizona, told Fox News Digital, "This is what the administration has asked for." He added, "The administration made it very clear, they weren't going to actually work with our constitutional authority, unless we did the vote. Fine."
In response to the Republicans' claims, Oversight Democrats released a five-page memo on Friday morning, citing a "mountain of evidence" that they believe exonerates Biden of any wrongdoing.
The memo read, "Rather than accept these facts, Republicans have resorted to cherry-picking and distorting facts in order to justify continuing this sham investigation aimed at satisfying the demands for retribution of President Trump who was twice indicted and now faces 91 felony counts."
