BREAKING: Senator Ron Johnson blocks $1,200 checks for Americans sought by Senator Josh Hawley.

Johnson cites the deficit.

Senator Sanders also pushing another round of stimulus checks. Much smaller checks are being discussed by bipartisan leaders to keep the plan under $900B while still giving hundreds of billions to smaller biz, etc.

Democratic leaders also back the stimulus checks, but had wanted it to be ON TOP of the $900B bipartisan package.

Hawley said Sanders would make another effort to send the checks, which are capped so wealthier people don't get them, later today.

Ron Johnson said that targeted aid to small businesses and people that are suffering makes sense, but said he objected to broad approach, and noted unemployment is 6.7%, which he implied wasn't that high.

Trump has at various times also talked up more checks, but where is he?
