Senate majority leader Mitch McConnell later meets behind closed doors with GOP senators later Tuesday as they negotiate negotiating terms.
The Senate is considering whether to allow a motion to call additional witnesses.
Since the impeachment process begins in a few days, the senators are still debating the procedural rules.
"I'm happy to join the president's team if that's what the president and that's what Pat Cipollone in the White House counsel's team wants; and if that's what the Senate wants", Jordan told "Fox & Friends".

Senators could be sworn in as soon as Thursday for the impeachment trial, according to CNN, citing Senate aides.
She said, "Now the ball is in their court to either do that or pay a price".
The 1999 impeachment trial of then-President Bill Clinton lasted five weeks. A fair trial involves witnesses and documents. McConnell has said he is against calling witnesses although he will allow fellow lawmakers to decide that after the initial case is laid out.
It takes just 51 votes during the impeachment trial to approve rules or call witnesses. The whole process will represent a test of Mitch McConnell's parliamentary and megalomaniac-wrangling skills, of Roberts's ability to appear impartial, of Trump's own limited self-control, and of party unity on both sides of the aisle.

The impeachment charges stem from Trump's request that Ukraine investigate former Vice President Joe Biden, a leading contender for the Democratic nomination to face Trump in the November 3 presidential election. A Ukrainian gas company had hired Hunter Biden when his father was vice president and the Obama administration's point man on Ukraine. No evidence of wrongdoing by the Bidens has emerged.
Some Democrats will be then appointed as impeachment managers in order to prosecute the US President in the Senate.
