Despite taking some steps to push for congressional term limits, President Donald Trump has run into almost insurmountable obstacles with congressional leaders -- much less enacting the required constitutional amendment.

Here's what Trump has tried: In April 2018, Trump cheered on a bipartisan group of lawmakers who met with him and discussed their support term limits for members of Congress. The lawmakers included Reps. Mike Gallagher, R-Wis.; Vicente Gonzalez, D-Texas; Jodey Arrington, R-Texas; Ro Khanna, D-Calif.; and Brian Fitzpatrick, R-Pa., CNN reported.

"I recently had a terrific meeting with a bipartisan group of freshman lawmakers who feel very strongly in favor of Congressional term limits," he tweeted. "I gave them my full support and endorsement for their efforts. #DrainTheSwamp."

The following month, some of the lawmakers who met with Trump released a proposal to limit senators to two terms and House members to six terms.

Several pieces of legislation were introduced in the Congress that just ended, but those would have to be reintroduced in the new Congress to be pursued further.

And as a constitutional amendment, the bar for enactment is especially high: two-thirds of the House and Senate and ratification by two-thirds of the states.

And congressional leaders are likely to remain an obstacle.

In a November 2016 press conference, Senate Majority Leader Mitch McConnell, R-Ky., was asked if the Senate would consider legislation to limit terms. McConnell responded, "I would say we have term limits now. They're called elections. And it will not be on the agenda in the Senate."

We checked with his office, and a spokesman said that McConnell's position remains the same two years on. McConnell's opposition alone makes it nearly impossible for the idea to be considered in the Senate while he's leader, which essentially puts the kibosh on the idea.

We also checked with the office of expected House Speaker Nancy Pelosi, D-Calif. A spokesman said he was unaware of any push from Pelosi's office to seek term limits. (In negotiations with fellow Democrats, Pelosi did agree to a two-term limit on her own speakership, but that's different from term limits for all members of Congress.)

If the movement for term limits gathers steam, we'll reconsider. But right now, strong opposition from the Senate leadership means congressional term limits rate as a Promise Broken.
