Colorado’s federal lawmakers want more information about whether President Donald Trump pressured former FBI Director James Comey to end an investigation, but none have joined the calls for possible impeachment proceedings as of Wednesday afternoon.

"As I have said time and again, where there is smoke, there is usually fire. The American people deserve answers now, and our allies deserve our loyalty,” Rep. Jared Polis (D-Boulder) said. “It is time President Trump do what is just and allow a special prosecutor to investigate. Everyone who cares about our democracy, and has nothing to hide, should request transparency throughout this process.”

House members from both parties in other states have gone further than Colorado’s delegation, openly calling for impeachment proceedings to be opened against the president.

Rep. Al Green (D-Texas) called for impeachment on the House floor Wednesday, and Rep. Justin Amash (R-Michigan) told reporters Tuesday that if the memo is true it would grounds for impeachment.

The allegation stems from a memo Comey reportedly wrote following a one-on-one meeting in February after a national security briefing.

The memo alleges Trump told Comey “I hope you can see your way clear to letting this go, to letting [Michael] Flynn go.”

Trump fired Flynn, his national security advisor, after it became public that Flynn mislead the White House about conversations he had with Russia’a ambassador.

The White House and the president have strongly denied that Trump tried to pressure Comey on this investigation or any other investigation.

Polis isn’t the only one calling for an independent investigation.

Reps. Diana DeGette (D-Denver) and Mike Coffman (R-Aurora) also reiterated their calls for someone outside of Congress, the FBI and the White House to take the lead.

“Only an independent inquiry, free from potential political interference, can get to the bottom of the matter,” DeGette said.

Sen. Michael Bennet (D-Colorado) also wants an independent investigation by a special prosecutor.

"Reports that the President asked the FBI Director to end the investigation are deeply disturbing,” Sen. Michael Bennett (D-Colorado) said. “Congress needs more information, including access to the memos from Director Comey and any recordings or transcripts from the White House. Comey also should testify publicly.”

Rep. Doug Lamborn (R-Colorado Springs) didn’t mention an independent commission or prosecutor. He called on the president to “stop the swirling media narratives around his actions by sharing the complete truth with the nation.”

The Senate Judiciary Committee requested Wednesday all records related to conversations between Comey and Trump. And the Senate Intelligence Committeesent a letter to Comey asking him to appear before them in both closed and open sessions.

Rep. Scott Tipton (R-Cortez) isn’t saying how he feels about an independent investigation. His office told us in a statement: “Congressman Tipton supports the House Oversight Committee's request for Mr. Comey's documents. Until he has access to them, the Congressman will not be commenting further.”

Sen. Cory Gardner (R-Colorado) gave a similar answer, saying that he “strongly” supports the senate intelligence committee’s efforts to get Comey to testify and seek any further relevant Comey memos from the FBI.

“We currently do not have all the information – and we need to see it before we comment further,” Gardner said in a statement. “It’s also important that this does not impact the ongoing investigation into Russia."
